qzdoom/src/info.cpp
Christoph Oelckers 9df27c7afd - Added an 'allcheats' CVAR. This will enable all cheats from all
supported games in any game being played.
- Changed Chex Quest DoomEdNum initilization so that all empty slots 
  are filled with Doom actors if they exist.
- Added missing spawn filters to Chex Quest items.
