Automatically restart mounts that failed

[Sploder12]

What are you trying to do? When a classic mount fails, it currently does not automatically recover. The current best option is to unmount then mount manually. It would be nice if the daemon automatically restarted the mount. Alternatively, having a way to restart a mount easily would be good to have.

What's your proposed solution? When the sshfs process exits due to an error, the daemon attempts to restart the sshfs process unless the error is unrecoverable.
