        CSP object-src should block plugin loads
        https://bugs.webkit.org/show_bug.cgi?id=57283

        This change is pretty straight-forward.  It's slighly unclear to me
        whether this patch is correct w.r.t. the code in DocumentWriter.  I've
        added a FIXME comment, and I'll investigate that case more in the future.

        Test: http/tests/security/contentSecurityPolicy/object-src-none.html
