Move Fallen to its own thing.

[QueenSuzie]

If you are adding or modifying an Auto Splitter, please fill out this checklist:

• [ x ] My Auto Splitter does not contain any malicious functionality and I'm entirely responsible for any damages myself. (Any kind of abuse in an Auto Splitter will result in an immediate ban.)
• [ x ] I am not replacing an existing Auto Splitter by a different author, or I have received permission from the author to replace the existing Auto Splitter.
• [ x ] The Auto Splitter has an open source license that allows anyone to fork and host it.

It makes more sense (to me) for differences in my modded category to have its autosplit differences on its own splitter instead of cluttering up the main splitter for the rest of the game, especially as any more differences are introduced.
