More SDAT Swap fixes, sorry.

SDAT Swap has been refactored to work properly under WINE.

The FoFi Graphics Editor has been updated to allow for easily changing which files a sprite points to. Also, it includes (and automatically applies) the FFC AP Fix patch now, sorry for missing that before.

The FoFi Graphics Editor has been updated to include the latest NitroPaint. Please let me know if there are any issues (well, let EchoSpaceZ know if you aren't him lol).

The FoFi docs are updated to include a little new info from EchoSpaceZ. But watch this space, as he appears to have exciting things planned in the future.
