Referrer Policy Header for CSS

Add the ability for CSS stylesheets to specify their own referrer policy via the HTTP header.


Previously, a CSS stylesheet would inherit the referrer policy of the document that referenced it. This is now no longer the case. Instead the "default" policy will be used unless overwritten via the HTTP header.
