Marisa Kirisame 1207748311 1.1 release:
- Hexen compatibility (Combiner Patch will be updated soon).
 - Environment Map shader fixes from Doom Tournament.
 - Buffed Stunner so it's actually useful. This goes against what the Unreal
   Bible indicated but whatever, the weapon would be useless otherwise.
 - "Superweapons" now have +ALWAYSPICKUP for consistency.
 - Sneaky Strife stuff:
   - Dispersion Pistol and Stunner have reduced alert radius.
   - Rename Peacemaker sprites to avoid conflict with peasant sprites.
