Committed patch #1168149 (Shared GM/MT-32 mapping) by eriktorbjorn as-is. This does the following:
- Replaces multiple identical MT-32-to-General MIDI mapping tables with a common one in MidiDriver.
- Changes Sky's GmChannel class to allow NULL instrument and velocity mapping tables, giving a 1-to-1 mapping without creating a dummy table.
