Add FrameLoaderClient::allowImages method to allow the client to overrule image loading policy on a per frame basis
For completeness, I'm also adding a Settings::areImagesEnabled. This is different from loadsImagesAutomatically as I explain in the patch comments.

As we discussed, either you or I owe Sam a test for this patch. We should be able to write the test at the same time as the test for allowPlugins.
