Add Category Information to GazelleGames about autodl-trackers

Looking at the list of categories, it's both possible to have a '-' character in a category and a '-' surrounded by spaces, so it'd definitely require a more advanced regex than that.

Edit: There are also some other characters in current categories that aren't covered. And then you have to consider the possibility of them being there even if they aren't now. Honestly, the ideal thing to do would be to ask for them to separate/move the category (technically called Platform on GGn) in a way to be more easily parsed.

As an extra thought, the same could be said for their release tags (i.e. '(English, Scene)'). Really, the entire announce could be much better formatted both for human and programmatic parsing.
