gbx: change hello logic. Before cards where deleted/newly created on every hello. Exception have been cards with good sids which never have been deleted. Even when they have been off forever.
     Now goodbye messages from peers are recognized. Further:
	- send chid/0000/ffff in CW message
	- signal cache use in CW message
