Adapted most multi-source plugins to the iAudio M3 keypad and screen. Doom and mpegplayer are disabled because of the not yet implemented greyscale library, and zxbox used 2-bit greyscale for now. * Slight optimisation for the (currently unused except on M3) 2-bit greyscale code in zxbox. * Simplified button definitions in chessbox.
