Disable the Referer header on resource requests by default
https://redmine.stoutner.com/issues/246 removed it on the loading of all URLs, but not for resource requests.

It looks like this can be done using `shouldInterceptRequest()`.
It might also be possible to remove other undesirable headers at the same time, but further testing will be required to be sure and to assess the impact on the loading of requests.
