Villager See, Villager Do

• Added new config 'Limit enchantments' (default true), that when false, will allow enchanted items to have any enchantments on them, not just those possible in vanilla. Closes #8.
• Villagers will now close any open trading screens when they pick up an item and re-roll their trades
• Villagers now try harder to throw items to a player rather than it dropping on the ground
• Refined some error logging
• Fixed villagers not returning rejected items as they should have been
• Fixed incorrectly logging error "Found rejected stacks that aren't in inventory:..."
• Fixed several trade selection issues that could cause prevent selection of valid items after an invalid item was rejected
• Reworked some internals to be easier to maintain and less prone to errors
• This is a BETA version: there were a significant number of internal changes and so there's a higher-than-normal chance that new issues were introduced
