- Changed D3DFB to explicitly request double buffering instead of assuming

that the drivers will treat a BackBufferCount of 0 as a request for
  double buffering.
- Fixed: Unsetting a cvar did not remove it from the list of tab
  completions.
- Added "" as a synonym for "nullimage" in SBARINFO.
- Fixed: MAKESAVESIG's stringifier in version.h did not work as expected.
  It stringified the passed macro name, not the value of the macro.
- Moved DCajunMaster off the DObject hierarchy.
- Changed DCajunMaster::getspawned into a TArray of FStrings. It was
  mysteriously being left pointing to uninitialized memory during the
  final GC at exit and crashing.
- Fixed: The code that removed hexdd.wad from the list of IWADs when
  hexen.wad was not present did not work.
