quakeforge/include/QF/keys.h
Bill Currie e81d690b51 [input] Create QF input library using keys.c 
This refactors (as such) keys.c so that it no longer depends on console
or gib, and pulls keys out of video targets. The eventual plan is to
move all high-level general input handling into libQFinput, and probably
low-level (eg, /dev/input handling for joysticks etc on Linux).

Fixes #8
