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
