`{network}` variable

Network name as exposed to the client.
I'd love to get this implemented because currently `[IRC] [irc.applecraftserver.com] <phroa> Hi there` takes up half the freaking screen in minecraft :P
Being able to condense that down to `[AppleCraft IRC] <phroa> Hi` would be great. I haven't tested this, but I'm reasonably sure I read the javadocs right on that.
