GM/GS Percussion Remapping
|Reported by:||SF/tbcarey||Owned by:||sev-|
Decided to break this up from the GS patch, since the two aren't really interrelated and there's no reason not to just commit it now. It only remaps notes 24-34 to specific GM drums so that they'll play correctly on GM/GS devices and emulate the way notes 23-34 are handled by the original interpreter.
