- Added a type check to Spawn(actorname,...) to allow it to print a

meaningful message instead of the nondescript 
  'Tried to spawn a class-less actor'.
- Converted AGlassJunk to DECORATE and made the spawn function a little
  more flexible so that replacing the shard is easier.
- Converted ABloodSplatter to DECORATE.
- Removed A_Jiggle because it never worked properly.
- Changed DECORATE parser to allow commas between arguments for multi-
  argument properties. For all newly added properties this format will
  become mandatory but for backwards compatibility it is optional for
  old ones.
- Added a check for negative indices to TAutoGrowArray::SetVal to prevent
  passing an index of -1 from crashing the game.
- Fixed: Morphing must clear the weapon's flash sprite.
- Fixed: Resurrecting a morphed player caused a crash.
- Fixed: Random sounds that recursively refer to themselves caused a stack
  overflow. Now they print a warning and get ignored.
