    theme: Use gnome-shell-sass as a submodule
    
    The sass sources now live in a project in GNOME, so they can
    be used in multiple projects like gnome-shell-extensions.
    Because of that, add gnome-shell-sass as a submodule of
    gnome-shell-extensions and remove the sass sources from the theme
    directory.
