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.
