   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.
