[IRCServices] Couple of Security Feature requests..

[Craig McLure]

Kinda simple really, Had a user who's recently been annoying, resulting 
in a network ban, this got the staff talking about possible evasion 
techniques..

Firstly, we've forbidden his nicknames, i may have to recheck the docs 
on this one, but if it doesn't already exist, can services provide a 
wallops when someone attempts to USE a forbidden nickname? (That one can 
be made into a module easily enough, other people may like it so it 
would probably be better in the core)

Secondly, a way to ban use of email addresses, and again, alert opers if 
someone attempts to use it.

These would help crack down on people attempting to evade bans, as they 
could be spotted easily :)

Thanks.
