- Merged a lot of these static destructor-only structs into regular

functions added to the exit chain with atterm so that they can be called
  in a deterministic order and not whatever order the linker decides to put
  them in.
- Fixed: DCajunMaster did not free its getspawned.
- Fixed: P_FreeLevelData() did not free ACS scripts.
- Fixed: Level snapshots were not freed at exit.
- Fixed: The save/load menu list was not freed at exit.
- Fixed: FCompressedMemFile needs a destructor to free the m_ImplodedBuffer.
- Fixed: G_DoLoadGame() did not free the engine string.
- Fixed: M_ReadSaveStrings() did not free the engine string.
- Fixed: Processing DEM_SAVEGAME did not free the pathname string.
- Added a check for truncated flats to FFlatTexture::MakeTexture() because
  Heretic's F_SKY1 is only four bytes long.
- Added a dump of the offending state to the "Cannot find state..." diagnostic.
- Fixed: FCompressedFile did not initialize m_Mode in its default constructor.
- Fixed: Heretic and Hexen status bars did not initialize ArtiRefresh.
- Fixed: PNGHandle destructor should use delete[] to free TextChunks.
