Inheritance of Keymaps

NOTE:
I found a backlighting/touchpad bug while testing this stuff. With the minimal setup shown in the above image, when switching to the COL keymap, the right-half LEDs only illuminate for the keys that are mapped on the COL keymap. The rest remain dark, but the left keyboard half stays fully lit up. If I tap a layer switch key, or if I detach/reconnect the touchpad, it resolves it.

Nice one!
