- Fixed: The pointer cleanup code must also check a sector's sky box pointers.

- Fixed: Right after teleporting P_SlideMove could cause player movement.
  Added a check for reactiontime to prevent that.
- Fixed: PainChances and Damagefactors were never freed.
- Added option to A_Chase that prevents the monster from moving.
- Fixed: The stained glass shards were missing the HEXENBOUNCE flag.
- Added some NULL pointer checks to AActor::GiveAmmo.
- Fixed: The FSwordMissile was missing the special damage handling that
  reduces damage when hitting a player.
