split out irc codes from client code.

[wraithan]

This moves the giant block of irc codes out of the client code and into its own file so that it is easier to read.

Included in #34

Following up on this. It was partially a stylistic change partially a functional change (500 lines of codes is intimidating when trying to dive into a new project's code). If there is anything I need to to do to get this merged, let me know.

Hey dude, since I've merged your documentation patch separately, this no-longer merges cleanly.

If I have time I'll resolve any conflicts manually sometime this weekend, but if you're really keen to get it rolling, it'd be great if you could fix this up into a clean merge :-)

[wraithan]

I can do that tonight after work. Should only take me a minute to rebase it.

[martynsmith]

This is just me "marking" this pull request as read, I'm not sure if there's a smarter way to do it, but it'll appear back on my "need to do something" list once you've fixed up the merge :-)

These should apply cleanly to master now. Sorry about forgetting about this.
