  42 **  Check for Condition After a Move
  43 **
  44 **      Various ship conditions are checked.  First we check
  45 **      to see if we have already lost the game, due to running
  46 **      out of life support reserves, running out of energy,
  47 **      or running out of crew members.  The check for running
  48 **      out of time is in events().
  49 **
  50 **      If we are in automatic override mode (Etc.nkling < 0), we
  51 **      don't want to do anything else, lest we call autover
  52 **      recursively.
  53 **
  54 **      In the normal case, if there is a supernova, we call
  55 **      autover() to help us escape.  If after calling autover()
  56 **      we are still in the grips of a supernova, we get burnt
  57 **      up.
  58 **
  59 **      If there are no Klingons in this quadrant, we nullify any
  60 **      distress calls which might exist.
  61 **
  62 **      We then set the condition code, based on the energy level
  63 **      and battle conditions.
