Add support for fetching xchan data by address.

Not entirely happy with it, have updated the signature of 
Client::fetch_stream and Client::url to take args, which are left out if 
they're not serializable (or empty, I hope.) Should probably use an 
Option instead, or maybe even two entry points for the api.
