* Updated to ZDoom r3690:

- Added the CCMD listsnapshots to show which maps have savedata stored.
- Added textual descriptions of the zlib errors.
- Fixed: FinalGC() needs to run before the type system is shut down.
- Fixed: Don't access class metadata at all in DObject::PropagateMark if the type system is shutdown.
- Fixed: If FCompressedMemFile::Reopen() fails, then it would try to double-free memory when deleted.
- Fixed: The text screen's color #6 should be brown, not dark yellow.
- Fixed: Direct ACS instructions need to tag their strings before lookup.
