50**  Schedule Ship.damages to a Device
51**
52**	Device `dev1' is damaged in an amount `dam'.  Dam is measured
53**	in stardates, and is an additional amount of damage.  It should
54**	be the amount to occur in non-docked mode.  The adjustment
55**	to docked mode occurs automatically if we are docked.
56**
57**	Note that the repair of the device occurs on a DATE, meaning
58**	that the dock() and undock() have to reschedule the event.
