combined JOIN and MODE

[Christophe Kalt <kalt@xxxxxxxxxxx>]

once again, I'm pointing you to

http://www.funet.fi/~irc/server/other.html which documents
2.9* changes to the client-server protocol.

2.9* versions have been using the JOIN/MODE combination
since the very early stage of development.  production
servers have used it for years now.

config.h supports a MIRC_KLUDGE #define because mIRC was
	* a popular client
	* unable to understand the new syntax

2.9.4 goes a little bit further in reducing bandwidth
associated with JOINs.  One of the aspects is that a client
creating a channel is now informed of its chanop status with
a combined JOIN/MODE.

Clients supporting the combined JOIN/MODE syntax should have
no problem with this.

Other clients should have no problem with this either, ^G is
an invalid character in channel names.  (RFC1459 section 1.3)
