/**
    SCORE

   Calculate what the player's score would be if he quit now.
   This may be the end of the game, or he may just be wondering
   how he is doing.

   The present scoring algorithm is as follows:
   (treasure points are explained in a following comment)
      objective:          points:        present total possible:
   getting well into cave   25                    25
   total possible for treasures (+mag)           426
   reaching "closing"       20                    20
   "closed": quit/killed    10
             klutzed        20
             wrong way      25
             success        30                    30
				total:   501
   (points can also be deducted for using hints or deaths.)
