    gnome-shell: don't announce nameless window if we have pending focus event
    
    Some users have complained that saying "window" is not especially
    helpful when entering the gnome-shell switcher and other views.
    We can now peak and queued events, so if the newly-activated gnome-shell
    window lacks a name and we have a pending focus event, don't say "window".
    
    See issue #226.
