Improve Tor Launcher's behavior if tor exits
Currently, if tor exits (due to a crash or kill signal), Tor Launcher just displays an error alert that reads "Tor unexpectedly exited." To restore the ability to browse, users must quit the browser and restart it themselves.
Maybe Tor Launcher should offer to restart tor. Vidalia provides a clear indication of status ("Tor is not running") as well as a "Start Tor" button.
