Added the forum cache. The rest of the code now uses it instead than firing queries on every request.

Added the ability for admins to delete forums.
Added the ability for admins to edit forums.
Added the Uncategorised Forum for topics with an ID of 0. Possibly for deleted forums in the future?
Added the uncategorised forum visibility switch.
Creating forums now has an anti-CSRF session check. The same is true with the newly implemented forum deletion and modification features.
Cleaned up some of the error code.
