Added the Group Creator.

Generated files should now be detected by Github. I'll work on making the detection method a little less ugly once Github lets me put that thing on something other than the first line.
Fixed a race condition in the Forum Creator.
Fixed a few forgotten error checks in permmap_to_query.
