Add flag to tor to verify config

Right now if you edit the torrc incorrectly and HUP tor, it dies (and only says so in the log file so you may not even notice for awhile. Anyways, it would be nice if tor had something equivalent to Apache's -t flag which says "verify my config and tell me what if anything is broken". That way we could have a torctl script which has a 'reload' option which would first verify the config and if OK, would HUP tor.
