Storm

Add some basic webapp-manual storm->hipchat handling. I will add an input box for the Asana URL tomorrow so that the bot will post the storm gif along with the Asana link.
Ha, because to kick the cycle off `stormwatch.go` uses bot.client.Say to write to the devops room, which the bot then hears, and then kicks of storm mode.... Plugins are only activated on messages, and well, this is like making the bot talk to itself to get it motivated ;)
