        <rdar://problem/7414396> Leopard & Tiger: Support closed caption in <video> element

        * css/mediaControls.css:
            Define closed caption toggle button.

        * rendering/RenderMedia.cpp:
        (WebCore::RenderMedia::updateControls):
            Create closed caption toggle button in display order.

        * rendering/RenderThemeMac.mm:
        (WebCore::RenderThemeMac::shouldRenderMediaControlPart):
            Don't require MediaControllerThemeQuickTime theme for captions toggle button.
            No need to check if the movie has video, a closed captions track is a video
            track.
