Files for Cataclysm MUD.

Cataclysm MUD is a continuation of tbaMUD/CircleMUD, which is built on DIKU MUD. Due to licensing issues with tbaMUD, all licensing attributions should remain the same and not changed from the original, pre-LGPL license model.

TO be clear: this is not an LGPL licensed fork.
