Update to ZDoom r905:

- Added Martin Howe's morph system update.
- Added support for defining composite textures in HIRESTEX. It is not fully tested
  and right now can't do much more than the old TEXTUREx method.
- Added a few NULL pointer checks to the texture code.
- Made duplicate class names in DECORATE non-fatal. There is really no stability
  concern here and the worst that can happen is that the wrong actor is spawned.
  This was a constant hassle when testing with WADs that contain duplicate resources.
- Removed some GCC warnings.
- Fixed: MinGW doesn't have _get_pgmptr(), so it couldn't compile i_main.cpp.
- Fixed: MOD_WAVETABLE and MOD_SWSYNTH are not defined by w32api, so MinGW
  failed compiling the new MIDI code.
- Fixed: LocalSndInfo and LocalSndSeq in S_Start() need to be const char
  pointers, since "" is a constant.
- Fixed: parsecontext.h was missing a newline at the end of the file.
- Fixed: Timidity::Channel::mono, rpn, and nrpn were not initialized. In
  particular, this meant that every channel was almost certainly in mono mode,
  which can sound pretty bad if the song isn't meant to be played that way.
- Added bank numbers to the MIDI precaching for Timidity, since I guess I do
  need to care about banks, if even the Duke MIDIs use various banks.
- Fixed: snd_midiprecache only exists in Win32 builds, so gameconfigfile.cpp
  shouldn't unconditionally link against it.
- Fixed: pre_resample() was still disabled, and it left two samples at the end
  of the new wave data uninitialized.
- Moved the xmap table from timidity/tables.cpp to playmidi.cpp. Now I can get
  rid of timidity/tables.cpp, which conflicts in name with the main Doom
  tables.cpp. (And interestingly, VC++ automatically renamed the object file,
  so I wasn't aware of the problem with GCC.)
- Added a Gets function to the FileReader class which I planned to use
  to enable Timidity to read its config and sound patches from Zips. 
  I put this on hold though after finding out that the sound quality 
  isn't even near that of Timidity++.
- GCC-Fixes (FString::GetChars() for Printf calls)
- Added a dummy Weapon.NOLMS flag so that Skulltag weapons using this flag
  can be loaded
- Changed the MIDIStreamer to send the all notes off controller to each
  channel when restarting the song, rather than emitting a single note off
  event which only has 1 in 127 chance of being for a note that's playing
  on that channel. Then I decided it would probably be a good idea to reset
  all the controllers as well.
- Increasing the size of the internal Timidity stream buffer from 1/14 sec
  (copied from the OPL player) improved its sound dramatically, so apparently
  Timidity has issues with short stream buffers. It's now at 1/2 sec in
  length. However, there seems to be something weird going on with
  corazonazul_ff6boss.mid near the beginning where it stops and immediately
  restarts a guitar on the exact same note.
- Added a new sound debugging cvar: snd_drawoutput, which can show various
  oscilloscopes and spectrums.
- Eliminated some more global variables (onmobj, DoRipping, LastRipped,
  MissileActor, bulletpitch and linetarget.)
- Internal TiMidity now plays music. Unfortunately, it doesn't sound right. :(
- Changed the progdir global variable into an FString.
