- Fixed: Wall scrolling interpolations incremented their reference count twice.

- Fixed: Before a level's thinkers are loaded all previous interpolations must
  be cleared.
- Fixed: deleted interpolations didn't NULL the pointer in the interpolated
  object. Also added all interpolation pointers to DSectorMarker to ensure
  that they are properyl processed by the garbage collector.
