Instead of having a previousState and a currentState, of which at most
two bits are used, use a single byte. This saves us a lot of code space,
and makes a number of things easier, too.
The helpers were redone as macros, since they are just bit checks now.

The INJECTED flag can be used by handlers to determine where the event
originated from: as a result of a direct keypress, or if it was injected
into the event loop some other way.

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
code marginally smaller, and the feature completely optional.

Briefly document the key event handling flow, to make it clearer how the
functions can be used.

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.
