Known Issues
============
- Mods designed for old versions like ExtraHeroes probably won't work off the bat, and probably need to be renovated for
  the new version. I'm not doing it. YOU do it.
- "Pistol Uses Slot 1 Ammo" is currently bugged for Duke's pistol. I want to fix this, but the Duke weapon code is a
  horrible stygian nightmare, and I'm honestly not sure it's possible without a complete rewrite.
