Cannot connect to pusher when network reconnects

[tgolen]

Problem

After being disconnected from Pusher for longer than two hours (so the authToken expires), when Pusher tries to reconnect, it uses the expired authToken to attempt to authenticate, and then fails. So after network reconnect, pusher remains disconnected.

Solution

Add code to the pusher lib to handle the reconnection scenario so it can properly get a new authToken

I'll try to throw on the 5 second authToken again and get to the bottom of this one.
