commit f76e0a1db689dadfe32f211002248d03416b3982
from: Alexander Barton <alex@barton.de>
date: Thu Jun 24 22:33:01 2010 UTC

Implement user mode "c": receive connect/disconnect NOTICEs

Users having the user mode "c" set receive NOTICE messages on each
new client connection to the local server as well as disconnects.
Only IRC operators (users having the mode "o" set) are allowed to
set the 'c' user mode.

These connect/disconnect messages can be useful for open proxy
scanners -- BOPM (http://wiki.blitzed.org/BOPM) is now functional
with ngIRCd, for example.
