May 30, 2009 (Changes by Graf Zahl)
- Rewrote IWAD detection code to use the ResourceFile classes instead of
reading the WAD directory directly. As a side effect it should now be
possible to use Zip and 7z for IWADs, too.
- Added 'EndTitle' nextmap option which goes to the regular title loop after
the game has finished.
- Added NOBOSSRIP flag. Note: we are now at flags6!
