Bill Currie 89f8dfce09 [input] Clear button inputs when IN_ClearStates called
This fixes the annoying persistence of inputs when respawning and
changing levels. Axis input clearing is hooked up but does nothing as of
yet. Active device input clearing has always been hooked up, but also
does nothing in the evdev and x11 drivers.
