YetAnotherForum Fix

If you're using (an excellent free forum package, which I'm using in a few places) the current version has a bug in the stored procedures that will cause all kinds of strange problems when you have a multi-board installation - what's going on is whenever a group is updated, there are some flags that are only allowed to be set on one user, like 'IsAdmin', and 'IsGuest'.  The shipping stored procedure wipes out all the flags and then sets the flag for one of the users - but ignores the fact that there may be multiple boards, so all the other boards lose their flags.

I didn't find this - details are in this forum post.  I did spend some time trying to figure out why my forums were acting strangely - guests were showing up as various real users.
