item cost/coins table

   -100: 1 coin
101-250: 2 coins
251-450: 3 coins
451-700: 4 coins
701-   : 5 coins

Therefore, to separate "medium level" weapons...
- under 100 if lousy
- over 250 if good


weapon ranges
   -350: short
350-700: medium
700-   : long

should these be changed because all the beams are short or medium
should the categories be different for beams than missiles?
(this one has "long range for a beam")
