  41 **  DOCK TO STARBASE
  42 **
  43 **      The starship is docked to a starbase.  For this to work you
  44 **      must be adjacent to a starbase.
  45 **
  46 **      You get your supplies replenished and your captives are
  47 **      disembarked.  Note that your score is updated now, not when
  48 **      you actually take the captives.
  49 **
  50 **      Any repairs that need to be done are rescheduled to take
  51 **      place sooner.  This provides for the faster repairs when you
  52 **      are docked.
