    shell-app: Make use of Keywords in search
    
    .desktop files have been designed for browsing, so the existing
    fields often produce insufficient results when used for search.
    gnome-control-center used X-GNOME-Keywords for that purpose, which
    has now been standardized as Keywords. It makes sense for us to
    support it in gnome-shell as well (and encourage its use outside
    of settings panels).
