Various fixes to the enchanting and loot system
- enchanted loot generated by mapgen now uses PseudoRandom for randomness - prevent fishing loot from generating loot 32767 times (!!!) when only 1 is needed - bows and fishing rods obtained from the treasure section of fishing loot are now enchanted - there is now a function to uniform enchant items other than books
