Move from irc 0.5.2 to irc-upd 0.6.1

The irc module does not appear to be very actively maintained, and has
quite a few issues causing issues in this project itself.

This fork, maintained by me, has a few fixes to some major issues
already.

Changelogs:

- v0.6.0 - https://github.com/Throne3d/node-irc/releases/tag/v0.6.0
- v0.6.1 - https://github.com/Throne3d/node-irc/releases/tag/v0.6.1

Should fix #199, #200, as well as some issues not previously noted
(crash if unbanning a user who is not banned, crash in circumstances
with a poor internet connection).

It may also allow us to remove our workaround for the quit and nick
events having all channels in the associated array.
