Resource links need to be versioned

[arschmitz]

In the jquery-ui and jquery-mobile api docs the resources are always assumed to be root. This is not correct as they can change version to version and break older versions.

http://api.jquerymobile.com/1.3/button/

this should be handled by https://github.com/jquery/jquery-wp-content/blob/master/mu-plugins/api-sites/rewrite-old-api-links.php but its not working.
