cubicweb #2491768 Add support for Cross Origin Resource Sharing [validation pending]

Spec can be found on : http://www.w3.org/TR/cors/

A sample use case for CORS is creating dashboards with JSON data exchange between various CW instances with different URLs (logilab.org and cubicweb.org for example). Modern browsers block AJAX queries outside of the originating domain.
