* Added support for the b.face keyboard
This commit adds support for the 60% keyboard from winkeyless, the
b.face. The basic keyboard layout as well as the RGB backlighting
works as expected; the per-key LEDs can be turned on or off but not
yet dimmed. A default 60% US-layout is included.
* Added link to the bface in the ps2avrGB README
