    app: add gimp_tools_blink_lock_box()
    
    Add gimp_tools_blink_lock_box() utility function, in a new
    gimptools-utils.c file, which takes a GimpItem, and blinks the
    GimpItemTreeView lock-box of the corresponding dockable.  This can
    be used to hint that the item's lock toggles are preventing it from
    being edited.
