* Properly allow includes for keymaps to allow defining
custom keycodes, and then adding them to the
keymap.overlay file.
* Fix keymap.c loading after build refactor.
* Fix for deactivating a layer working properly.
* Fix default keymap to put transparent in proper spots to
make raise/lower keycodes work as expected.
* Add custom raise/lower keycode handling to default
keymap.
