Instead of doing gamma correction when setting a LED color, do it elsewhere,
when talking to the LED hardware. This way, both the programmer, and the
end-user will deal with the unaltered, raw RGB values, and neither has to care
about when and how gamma correction is applied.
The counterpart of this will be in KeyboardioScanner, that re-introduces gamma
correction on that end.

Instead of calling the `.write` method of `ConsumerControl`/`SystemControl`,

However, since `.press` always sends a report, and so does `.releaseAll`, we

the consumer/system key, when the triggering key is released too. Not doing so
makes the key stuck, as we never release it, and that will upset the operating

Instead of going through all the active layers each time we are looking for a

happen far more often than layer switching.
This comes at a cost of ROWS*COLS amount of memory, and a bit of code, but on
the flip side, the lookup operation is now O(1), which is a very nice property
to have, if you want responsiveness. Changing layers is marginally slower,
however, but even with 32 active layers, doing the computation once, instead of
potentially many dozens of time, is still worth it.

`___`/`XXX`, respectively. This makes it possible to space keys in a nicer way
in the source layout files.

`keymapEntry.rawKey` contains the target layer, but offset by
`MOMENTARY_OFFSET`. That value must be subtracted from the value before
comparing it to anything, or switching to another layer.

Instead of having a primary and a temporary layer, store the state of at
most 32 layers in a bitfield. These can be individually turned on and
off, and key lookup starts from the top, and goes downwards until the
default layer to find a non-transparent key.
This allows one to reuse a partially transparent layer: set the default,
and the transparent parts will be reused. The numpad layer was updated
accordingly.
Having an interface to the layer switching things also makes it easier
to build other behaviour on top of these.
As part of the rework, layer handling was moved to a separate file, and into its
own, full-blown handler. Furthermore, we now use a single bit for all keymap
events.

Instead of registering the default handler late, always call it at the end if no
other handler took care of the event. This makes it less of an issue to order

Introduces the RESERVED bit, a bit reserved for plugins. If it is set, the core
handlers will not handle the event.
Also rearranges the SYNTHETIC bits, to make slightly more sense. In practice,
this means that LED_TOGGLE was promoted to a flag bit, under IS_INTERNAL.
The handler that deals with synthetic events was updated to look at the flag
bits in an order that does not cause confusion, and preparations were also made
to turn it into an independent handler on its own (but that step has not been
taken yet).
This is just groundwork to clean things up, and make the event flow easier to
follow.

We can't register hooks from constructors, because there is no guaranteed order
in which the objects will be created. So it may well happen that the Keyboardio
object gets created later, and zeroes out everything. Or it gets created first,
and registers the default handler as the first one, making all the others
pointless.
Instead, we create a KeyboardioPlugin class, that has a `begin` method. This is
responsible for setting up the hooks and whatnot. To make things simpler (for
some values of simple), a `Keyboardio.use` method is introduced, which, when
given a NULL-terminated list of plugin object pointers, will call the begin
method of each.
All LED effects and other plugins that used to register a static object now use
an extern, and had their initialization moved to the `begin` method.
The end result is not the nicest thing, but it works. We can try figuring out
something nicer later.

Wraps the value LCTRL & friends in parens, so that they can be easily passed on

Add a number of helper macros that aid in constructing the Key code for
keys with modifiers held. These can, of course, be embedded in each
other, so to have a key on the keymap that has all currently supported
modifiers pressed, along with `X`, one would write:
`LCTRL(LALT(RALT(LSHIFT(LGUI(X)))))`

Instead of calling loop hooks before anything else, including scanning

Since macros and other injected keys do not clear the report, we need a way to
release keys. The new `release_key` function does just that, similar to how
`press_key` does it for key presses. It is called by the default event handler
when the `keyState` toggles off, and has the `INJECTED` bit set.
The reason behind this is that keys that will need this special treatment will
always be injected keys. And those injected keys that do not need this
treatment, can be handled by an event handler prior to the default.
This should fix the macros not releasing keys issue.

Instead of hardcoding the macro actions into the core firmware, use a
`macroAction` function that is marked weak. This makes it possible to override
the function from Sketches, and implement the handlers there.
While there, also made sure that the `macroAction` is always called, with
`keyState` argument appropriately set. With this, macro actions can trigger on
keyup, or while held, or anytime the implementor wants, not just on keypress.

When one adds or removes a layer from a keymap, the keymap size has to
be adjusted in the call to `Keyboardio.setup()`. This is easy to forget,

This way, one does not need to remember to update the size anywhere.

Save the seen state in EEPROM, so that the boot animation is displayed

The primary reason for the move is to be able to disable mouse keys
completely, and not even compile them in. For this to work, it needs to
be in a separate library, otherwise it will always be included, even if
not active.
So, this patch turns mouse-keys into a simple plugin, included with the
core firmware! This makes the default event handler a bit simpler, the

For those who'd like to work with C arrays, instead of generating
layouts from some other source, the `KEYMAP` macro makes it easier to
define a layer. The parameters in the macro arguments are arranged in
such a way that they can be formatted in a way that matches each hand
more closely. Similarly, a `KEYMAP_STACKED` is introduced, where the
hands are under each other, not side-by-side.
This is just aesthetics, for the C-savvier users.

It would be nice if LED effects could be activated via their object, not
just their number, so that one could write - say, in a macro -
`myEffect.activate()`, and have it become the active mode.
To implement this, `LEDControl_` gains an `activate` method, that takes
a pointer, finds it in the mode array, and switches to its index (if
found). `LEDMode` gains an `activate` method too, which uses
`LEDControl`s new method of the same name to activate itself.

While this function had a declaration in the header, it lacked an
implementation. With this patch, `key_led_map` moves to the cpp from the
header, and the function gains an implementation.

similarly to the other arities.

Recreate LEDControl as a class with pluggable parts, similar in vein to
the event handler and loop hooks. Except in this case, only the current
effect runs at any one time, the current one.
All existing effects were separated out into plugins, and the default
firmware example was updated too. All of them were pretty trivial, save
the special NumLock effect: that one also installs a loop hook, and
switches the LED mode if need be. Its setup function also skips to the
next effect, if the mode was selected manually.
Behaviour should be the same as before, but LED effects are now
pluggable, at the cost of some code and data size increase.

Instead of not handling the case where the LED index is out of range,
and thus producing a warning, return a black color instead. It's as good
as anything else, but at least gets rid of the warning.
And, it goes hand-in-hand with the set counterpart, which, in a similar
case, does nothing: thus the out-of-range LED remains black forever.

Do the mappedKey lookup earlier, in handle_key_event, so that if any of
our handlers need to look at the mapped key, they do not have to look it
up themselves. This simplifies plugged hooks considerably, as they can
always assume that the mapped key they receive is correct. They still
receive enough information to do the lookup themselves, though, if they
ever need that.
Additionally, in handle_key_event_default, baseKey is only looked up if
mappedKey was NoKey. This is so that hooks can defer to this function,
via handle_key_event, setting their own mappedKey, without having to
worry about setting a row/col that would map to a special key on the
base layer.
Fixes#39.

To make replacing work sanely, we first NULL out both the eventHandlers
and loopHooks arrays in the Keyboardio_ constructor. This allows the
replace functions to just run through the whole array, and either see
hook pointers there, or NULL. So they don't need to be afraid of garbage
being there.
This makes the replacing very easy: run through the array, and replace
the first occurrence of the old hook with the new. This further
simplifies addition: the old hook we pass in, will be NULL. If we run
out of space, it silently fails, like before.
Replacing hooks is important for cases where one wants to build features
that can be toggled off, or their behaviour otherwise changed at
run-time. In this case, the most efficent way is to replace the hook,
which is what these new helpers allow us to do.
This closes#36.

There are scenarios where one would want to inject a keycode into the
event handler chain, restart the processing from scratch, but with a
keycode different than what the lookup would normally yield. For
example, with one-shot modifiers, a feature one may wish is to be able
to turn the one-shotness off, and have them act as normal modifiers.
This is easily done, if we can remove the one-shot markup, and let the
event handler process the resulting code as-is.
This makes that possible: in a custom event handler, just call
handle_key_event() with the first argument set to the desired code, and
the rest left unchanged. This makes it possible to inject events: not
just register keycodes with the HID, but inject synthetic events,
something much more powerful.

This moves the layouts to the sketch directory, so that other sketches
can easily use a different keymap. In the process, not much had to be
changed, and a number of things still remain in the core that assume the
default keymap (such as the NUMPAD_KEYMAP thing in LEDControl.cpp), but
this is a first step.
The downside is that the keymap is no longer static, because that would
conflict with the extern declaration, and the NUMPAD_KEYMAP is a byte,
instead of a compile-time define.
Alltogether, the difference is small enough to be acceptable.

Moved the library sources into src/, and the sketch into examples/. This
makes it easier to use the project as a library, and the default
firmware sketch shows up in Arduino IDE's Files/Examples menu. This in
turn, has a very neat side effect: an end user can start from this
example, and when they save it, it will be saved to their Sketchbook,
and the library can be updated independently, without having to worry
about conflicts.
Having the Sketch separate from the sources also paves the way for
moving the keymap there.
As far as Arduino IDE dependencies go: this requires Arduino IDE 1.6.7+,
the same minimum version required previously.
