Instead of calculating the time delta each time we check for a timeout,
pre-calculate the projected ending time, and compare against that.

Instead of calculating the time delta every time we want to check if the
timer elapsed, calculate the projected ending time at the start, and
compare against that.

Instead of calculating the elapsed time every time we check the timer,
calculate the projected end-time when we start the timer, and just
compare millis() against that.
Also removes the `.configure()` method, in favour of making the
`timeOut` property public.

Instead of doing a substraction and a compare in the if check, whenever we reset
the timer, add `syncDelay`, and compare against the timer only. Should result in
marginally better performing code.
Thanks @obra for the suggestion!

Because `led_sync` is a major cause of slowness, do not sync every cycle. In
most cases, it is pointless to sync 100 times a second, about 60 - or even 30 -
may be more than enough.
For this reason, introduce a timer, and a settable delay: we'll only call
`led_sync` once the delay's up. It can be set to 0 to call it every time, but
defaults to 16 (for about 62 syncs/sec), as a safe bet.
This speeds the loop up dramatically, except for the few exceptions where sync
is called.
Fixes#1.

The `CRGB` macro takes rgb values as arguments, in this order, and creates a
`cRGB` instance with the components rearranged to fit the ordering of the
hardware (in the case of the Model01, bgr).

The `USE_PLUGINS()` macro is a clever hack, to make it seem like
`Kaleidoscope.use()` is type-safe. It pushes its arguments into an appropriately
typed array, so anything that does not fit the criteria, will trigger a compiler
error.
It then never uses the array, and passes the plugins over to
`Kaleidoscope.use`, adding the trailing `NULL`, making it even easier to
use.
Since the array this macro creates is never used, the compiler will
optimize it out fully. As such, by using this macro, we incur neither
any size penalties, nor any run-time penalties. Everything happens at
compile-time.
Fixes#100.

Do not store the previous layer state, and instead of updating only when
the layer changes, just update anyway. It's not that costy anymore, with
the recent `Layer.lookup` optimisations.

To make things easier, just include the main header. It includes
everything else we need, and this way we do not need to cherry pick, nor
care if any of the other headers move, disappear, etc.

Having the hooks, and the hook methods in the Kaleidoscope object means
we don't have to litter the definitions of the arrays around, and that
the hooks are more tied to the object. We pollute the global namespace
less, and having them in the object means that the hook helper functions
will not be optimized out if not used within the Kaleidoscope repo.
All in all, this saves us about 56 bytes of code, allows us to remove
some hacks, and pulls things that are closely knit, closer together.
While there, also changed the name of the `custom_handler_t` and
`custom_loop_t` types to `eventHandlerHook` and `loopHook` (both under
the `Kaleidoscope_` class), to better reflect what they are for.

The plugin.h header only defined the KaleidoscopePlugin class, and while
there was a reason it was separate from Kaleidoscope.h, that reason is
long gone. Merge it there, and remove any reference to plugin.h, as it
is not needed anymore.

Since we pre-fill the cached `keyMap` with the value of `DefaultLayer`, there is
no need to check that layer again, looking for a non-transparent key. Whatever
is there, will be used anyway.
This way we save a cycle for keys that are transparent everywhere but the
default layer.

We fill the cached `keyMap` with the value of `DefaultLayer`, so if that is the
only layer active, then we can bail out early.

Instead of going through all the active layers each time we are looking for a
key, whenever we switch layers, compute the effective keymap, and store the
indexes. This makes the lookup a considerably faster operation, and lookups
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.
We could further reduce the memory requirements if we stored more columns per
byte, but that's for a future optimization.
