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