New forum setup

[perk31]

I've modified the forums into two possible configurations for review.

The first section, Nested Boards, is just that.  The main sections, game and another game, represent the top level and each has forums associated with that particular game or topic.

The next two, Chaotic Abyss Persistent World and Chaotic Abyss NWN Mod, are categories with several boards placed in the category.  Boards in a category can also be nested.

Either setup can be expanded or closed.

Please post your comments and which setup you prefer.
