[hybrid] +R patch

[Martin Pola]

Hello

I have taken a patch for an old version of ircd-hybrid and ported it to ircd-
hybrid 7.3.1. Basically what it does is that it adds the channel mode +R. That 
mode takes one parameter, a user host in the form of nick!user at host.

If a channel becomes opless, the server will try to see if there is anyone 
from the +R list in the channel. If so, it will op the person with least idle 
time.

Here's the patch:

The time between the checks should probably be changed to 1800 or 3600 
seconds; it's set very low right now so that people testing it don't have to 
wait for the reopping to occur.

Is this something that could be in either contrib/ or in the official release? 
It's possible to turn it off in ircd.conf, in the same way as with +e and +I.

Kind Regards,
Martin
