Disconnecting from HipChat

[MattMencel]

My Lita bot disconnects from HipChat fairly regularly. The debug looks like this for each of the rooms when the disconnect happens.

Similar problem, different spot. No reconnect. Hipchat's xmpp service had some issues today and lita threw the following. Ideally it would reconnect. Alternatively, lita could die and some other god process would restart it. As it is, it's take manual intervention.
