gzdoom/src/p_doors.cpp
Christoph Oelckers 15681d0588 - Added a StartConversation special that allows automatic activation of Strife 
dialogs.
- Added Thing_Raise special that allows Arch-Vile like resurrections from scripts
  or DECORATE states.
- Added a RadiusDamageFactor property for actors. This replaces the hard coded
  factor of 0.25 for Hexen's players.
- Added new SpawnProjectile function to ACS. It's the same as Thing_Projectile2
  but the projectile is specified by name, not spawn ID.
- Added MAPINFO option to set the compatibility flags. If this is done these
  explicit settings will take precedence over the compatflags CVAR.
