- Added support for ST's QUARTERGRAVITY flag.

- Added a generalized version of Skulltag's A_CheckRailReload function.
- Fixed: DrawImage didn't take 0 as a valid image index.
- Added Gez's RandomSpawner submission with significant changes.
- Added optional blocks for MAPINFO map definitions. ZDoom doesn't use
  this feature itself but it allows other ports based on ZDoom
  to implement their own sets of options without making such a MAPINFO 
  unreadable by ZDoom.
