remove superfluous ws-hostname parameter from notebook...

remove superfluous ws-hostname parameter from notebook This made the notebook server artificially and unnecessarily brittle to tunneling, and non-local hostname resolution. The ws_url is now defined based on the Origin of the request. This allows tunneled hosts and ports to preserve connections, as the ws_url always matches the one in use by the client. Implemented as a property, to facilitate future cases where it might behave differently.
