BIG FEATURE - MULTIPLE GROUPS

Users can now be assigned to multiple groups.  Thanks Yu!
Break out the Bob Marley!!

Otherwise groups work more or less like they did before.

This has been pretty well tested by Yu and myself, but since Yu started
uncovering lots of existing groups bugs it's possible there may be still
a few corner cases still lurking here and there.

Please help test this thoroughly for 1.6!!
