function _restws_determine_router_item in RESTful Web Services 7.2

Reroute requests that come from *.{format} paths. For example /node/2.json will need a correct page callback to be treated as a restws request.

Also, the restws_basic_auth module will need to use this function as well to perform this again after logging a user in.
