Add a button to switch tor circuits.
Currently, if things are taking a long time to load or timeouts are occurring, you have to completely shut down the application and restart it in order to get a new tor circuit. This seems really inefficient when there could just be a button somewhere in the user interface to do so.

Edit: Add an information dialog to the effect that it can take X time to re-establish the connection where the user must press an OK or cancel button.
