Update of /cvsroot/scummvm/scummvm/sound
In directory usw-pr-cvs1:/tmp/cvs-serv12689/sound

Modified Files:
	mididrv.h mididrv.cpp 
Log Message:
First commit of the OPL2 MIDI driver (to have MIDI music without
requiring any OS-level MIDI support).

This was taken from AdPlug.

This is *very* buggy for now (well, it works, but it sounds just plain
ugly :-) ).
