- Fixed: Skin definitions were never freed.

- Fixed: Names in terrain definitions were never freed. Replacing them with
  FNames would have been a good idea anyway.
- Fixed: The lock definitions were never freed.
- Fixed: FDoorAnimation was missing a destructor.
- Fixed: animation and switch definitions were never freed.
- Replaced all other places where FindType was used with FNames with 
  IFindType.
