Update to ZDoom r1229:

- Separated low level sound code from all high level dependencies.
- Separated low level sound channel class from high level class which now
  is just a subclass of the low level class.
- Moved some more high level sound logic out of FMODSoundRenderer:
  The rolloff and channel ended callbacks now call functions in s_sound.cpp
  instead of working on the data itself and GSnd->StopSound has been replaced
  with S_StopChannel.
- Changed compilation for g_doom, g_heretic, g_hexen and g_strife folders so 
  that all files are included by a central one instead of compiling each one 
  separately. This speeds up the compilation process by 25% when doing a 
  complete rebuild in Visual C.
- Cleaned up some include dependencies.
