Subject: Start moving towards final 0-10 spec: * marked preview spec as 99-0
 to distinguish it from 0-10 (which will now be used for the final version) *
 modified python client to treat 99-0 as 0-10 for now * modified broker to
 have two paths for the two different versions: 99-0 uses PreviewConnection,
 PreviewConnectionHandler   and PreviewSessionHandler which are straight copy
 & pastes of the Connection, ConnectionHandler and SessionHandler now  
 associated with 0-10 (so we can migrate the 0-10 path to the final spec
 without affecting clients working with the preview   version)
