Separate the keymap layout from the core firmware

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.
