Fixes #13: UTC vs not UTC, I don't know which one is right, but let's pick one!
Big overhaul again! Replaced fluffle's goirc library with velour/irc.

Hopefully this new library will provide me with some benefits such as being able
to actually get and respond to a WHO message. Yet to do is to fix sendMessage to
be a channel on Bot with a goroutine that formats and sends messages on. Also,
figuring out how to handle the WHO response and populate users.
