Modify Views to handle both ContentQuery and LocationQuery

The application/vnd.ez.api.ViewInput+xml media type must be changed to accept a "version=1.1" argument (either using the same handler, or with a new one).

Version 1.1 accepts ContentQuery and LocationQuery instead of Query.

The response, application/vnd.ez.api.View+xml, must be changed to include either Content or Location objects (see specifications).
