Subject: * Output XmlRpc error message if user server gets a fault response
 from the region server on login * This will make it more obvious if one
 accidentally starts one's region server in standalone rather than grid mode
 but then tries to login to a grid (as I am wont to do) * We are now sending
 back a fault code (-32601) if no xmlrpc method is found rather than an
 ordinary message
