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