Subject: Plugin rework 2: (all) Compile-time keyboard configuration, for Ondio
 adaption. (all) Now using the default event handler, standard placement is
 now in switch() default case. (minesweeper,pong,snake,snake2) added USB
 handling. (mandelbrot,mosaique) Fixed return value. (minesweeper) fast moving
 with button repeat. (oscillograph) Fixed cleanup in USB case.
