gstreamer1: reorganize options selection menus

gstreamer adds many module and library options to the top-level multimedia menu. These changes push the individual plugin modules and libraries to a secondary selection page depending on the main package choosen (libs, base, good, bad, ugly). Utils remains a top level package. Options to select ALL have been added rather than implied.
