* Updated to ZDoom 4285:

- Re-fixed r4279.
- Added three new ACS functions: GetUserCVar, SetCVar, and SetUserCVar.
- Added edward850's patch to cope with stalled network games.

* Updated to ZDoom 4289:
- Added parentheses for clarity.
- Fixed potential uninitialized access in FMapInfoParser::ParseEndGame().
- Fixed: 4, 2, and 1 bit grayscale images weren't properly supported.
- Fixed: Valgrind uninitialized memory error and a signed/unsigned warning.
- Just remembered that the true color stuff generates textures differently.  Changed the previous commit to expand 1, 2, and 4 bit grayscale images while reading the PNG instead of changing the palette.
