It's tied now, but can't we step by step untie it so it can be
integrated with the Horde Framework? Would be extremely
nice to make a general horde.Moderation class that can
handle moderation in most apps. Maybe one would be forced
to overload some of the horde.Moderation member functions
in e.g. kronolith.Moderation, but I think the main functionality
would be the same for most apps.
