[IRCServices] IrcServices enforcing +R

     Okay, here's my proposal.  The ChanServ "mode lock" functionality
will enforce locked modes at all times, performing the following actions:

   - When a client attempts to change the state of a locked mode (off to
     on, on to off, or changing parameters of an active mode), ChanServ
     will reverse the change.

   - When a client joins an empty channel with one or modes locked on,
     those modes will be automatically set on the channel.

   - If a client attempts to join a channel to which the mode lock denies
     them access, ChanServ will kickban the client from the channel.

If this enforcement is not desired, the mode lock functionality should not
be used.

     Conveniently, this is how Services already works. (:

P.S. If you disagree with my decision, you are of course free to write
(and distribute, if you so choose) a patch.  That's what open source is
about, after all.  You would, however, be well advised to consider the
varied effects of netsplits and netjoins, particularly with respect to
colliding channels and clients in them at netjoin time.
