- Fixed: The save percentage for Doom's green armor was slightly too low

which caused roundoff errors that made it less than 1/3 effective.
- Added support for "RRGGBB" strings to V_GetColor.
- Fixed: Desaturation maps for the TEXTURES lump were calculated incorrectly.
- Changed GetSpriteIndex to cache the last used sprite name so that the code
  using this function doesn't have to do it itself.
- Moved some more code for the state parser into p_states.cpp.
- Fixed: TDeletingArray should not try to delete NULL pointers.
