Please add Control Socket support

Since 0.2.2.29-beta, last remaining details to enable "Control Socket" by default on Tor have been sorted out.

This feature enables users inside Tor's group to establish a local unix socket connection to control or monitor its behavior, with no extra authentication required above basic POSIX permissions.

This is mayor feature for everyone attempting to experience or bring a painless-almost-zero-conf integration with Tor.

Since this introduces the capability to start arm with no configuration, adding Control Socket support would definitely be a great goal for end users.
