- updated resources to DX9
- completely rewritten headers (DX9 compat.; look much nicer now ;=)
- removed IDirectMusicSong and IDirectMusicMelodyFormulationTrack
  (which are removed from DX9; weren't implemented in DX8 anyway)
- combined/simplified IDirectMusicSomething / IDirectMusicObject /
  IPersistStream for objects that support loading
- implemented IDirectMusicObject on all such objects; via generic
  functions
- combined IDirectMusicTrack(8)/IPersistStream on all tracks
- fully implemented IDirectMusicContainer (at least 90% if there are
  no private interfaces)
- implemented IDirectMusicCollection (99% work & MS compliant
  behaviour; except for instruments)
- tried to implement IDirectMusicInstrument (unfortunately uses some
  dirty private interfaces... :(
- added dswave.dll; DirectMusic Wave
- some changes in style
- many, many more ;)
