Well, I decided to do it anyway. I know cras said he was planning to
do it for 0.9, but I want it *now* not some time in the future ;-).

I've got a patch that adds support for the 005 numeric, puts the
data it sends into a glib hash and makes use of CHANMODES, PREFIX,
CASEMAPPING and MODES. Other values are usable from the glib hash
in C or the $server->isupport method in perl scripts.

Please note that I cut lots of corners doing this with the rationale
that if this was planned for 0.9 bits of Irssi's internals could be
changed to suit more dynamic support for things like this.

Hopefully this also makes some patches such asthe ones to add support
for other prefixes obselete..

The patch is a bit big for a mailing list so it is at
http://babylon.otherwize.co.uk/irssi-isupport.diff

It was based on the internet draft at:
http://www.ietf.org/internet-drafts/draft-brocklesby-irc-isupport-01.txt
But hopefully most of the stuff it deals with is consistant across
servers anyway.
