parameters. These seem to be used primarily to restrict percussion

instruments to specific notes.
- Changed note velocity to not use the volume curve in recompute_amp(), since
  this sounds closer to TiMidity++, although I don't believe it's correct
  MIDI behavior. Also changed expression so that it scales the channel volume
  before going through the curve.
- Reworked load_instrument to be less opaque.
- Went through the TiMidity code and removed pretty much all of the SDL_mixer
  extensions. The only exception would be kill_others(), which I reworked
  into a kill_key_group() function, which should be useful for DLS
  instruments in the future.

- Added support for the GUS patch format's scale_frequency and scale_factor
parameters. These seem to be used primarily to restrict percussion
instruments to specific notes.
- Changed note velocity to not use the volume curve in recompute_amp(), since
this sounds closer to TiMidity++, although I don't believe it's correct
MIDI behavior. Also changed expression so that it scales the channel volume
before going through the curve.

April 15, 2008 (Changes by Graf Zahl)
- Added translation support to multipatch textures. Not tested yet!
- Added Martin Howe's morph weapon update.
