Overview

When I click on the opt-in button (and optionally navigate through the new IRC user wizard
described in issue #291), Hubs sets up an account for me in the IRC bouncer and I am
logged into the IRC network and join the channels the Hubs I'm a part of map to. I can then
see up to the last N messages in the channel, where N is configured by the Hubs administrator
in the server settings.

Implementation

This work is purely on the web server. Once a user has successfully opted in
and provided all the necessary data, an account should be created in the bouncer
for them. This needs to take into account what channels they should be in based
the hubs they are currently in.

The bouncer we plan to use is ircb. However, there is currently no API documentation and I am uncertain if the APIs we need to accomplish this task are present, so the first step for this issue is to ensure ircb is ready. Any issues found should be amended to this issue.
