No obvious way to restart Tor after dialog dismissed
When running Tor Browser 6.5a6-hardened, sometimes the Tor daemon disappears (always because of the Linux OOM killer I think). Usually I restart from the "Tor unexpectedly exited" dialog and everything is fine, but last time I accidentally dismissed that dialog and found no way to recover from this situation. I had to restart the browser completely, which was annoying because I had tabs open and some text typed in a form and I don't want any of this state on disk.
The "New Identity" and "New Tor Circuit" commands should pop up the "Tor exited" dialog if the daemon's not running, because what are they going to do otherwise? And how about putting a "restart" button on the "Proxy refusing connections" page?
