**  DOCK TO STARBASE
**
**      The starship is docked to a starbase.  For this to work you
**      must be adjacent to a starbase.
**
**      You get your supplies replenished and your captives are
**      disembarked.  Note that your score is updated now, not when
**      you actually take the captives.
**
**      Any repairs that need to be done are rescheduled to take
**      place sooner.  This provides for the faster repairs when you
**      are docked.
