    app: Fix CTRL+Q and ALT+A handling
    
    For some reason we were doing:
    
    event.state & Gdk.ModifierType.MODIFIER_MASK == TARGET_MASK
    
    while Gdk.ModifierType.MODIFIER_MASK should not be involved:
    
    event.state & TARGET_MASK != 0
    
    This change fixes the regression of CTRL+Q and ALT+A not working against
    recent Gtk+.
