- Do a 'full' remove of detached sides/sectors on opening a map
- Improved ZDoom support:
- More text lumps recognized
- List of keywords for various ZDoom languages updated
- DECORATE parser is now able to find sprites from states in the same way as Doom Builder 2
- Sprites from states can be found even if the lump does double-duty (e.g. BOS2A1C1 from doom2.wad will be found correctly for the BOS2 A state)
