Add a Integration feature for IRC (two-way sync between gitter room and a designated IRC channel)

https://github.com/gitterHQ/irc-bridge is great to have but it would also be great if the gitter UI provided an Integration for IRC— to support two-way sync/mirroring between a gitter room and a designated IRC channel on freenode or some other IRC server.

What I mean is something pretty much like https://github.com/finnp/gitter-irc-bot but that users don't need to run an instance of themselves—instead the Integration UI would provide a way to set up something similar.
