    build: Allow disabling the panel applet
    
    The plans for GNOME 3.0 currently do not foresee the presence of a
    "gnome-panel applet" in the UI; also, some GNOME-based platforms (like
    Moblin) do not use the gnome-panel at all, even though they still ship
    the Dictionary application.
    
    For these reasons we should provide a way to optionally disable building
    the gnome-panel Dictionary applet.
