Add debugging options to sbws torrc
We should set the following torrc options for better logs:
# useful logging options for clients that don't care about anonymity
'SafeLogging': 0,
'LogTimeGranularity': 1,
'ProtocolWarnings': 1,
I also mentioned some of these options in: https://github.com/torproject/sbws/issues/146 But they never made it into the pull request.
