Prior to this commit, the IRC service would dutifully notify you of
every push to every branch. This allows you to limit, via
comma-separated regexes, which branches will notify via IRC.
NOTE: It's possible that a , separated list of regexes could cause
problems if people want to use a , in the regex. If this is an issue,
I'll add a field to specify the delimiter.
