I'm moving all my 4x12s to the same keymap since I pretty much use it across all of them anyway, regardless of whether they're split or not. Gotta get the LAYOUT lovin', yo.

This revision includes this documentation and introduction of the individual RGB mode keys in the ADJUST layer.

Still to do:

Enjoy this revision; figure out new things later.
