        MediaPlayerPrivateQuickTimeVisualContext should use the Application Cache during load.
        https://bugs.webkit.org/show_bug.cgi?id=57047

        No new tests.

        When loading a URL, checkk osee if the Appplication Cache has a version of that URL
        stored; if so, use the local path to that cached media instead of the remote URL.
