TradeManager

• Added a new setting (in the UI) for each Villager Type called "Preferred Currency" and "Offered Currency"
• Added a new setting (in the vanilla-override config) called "Remove-Vanilla-Enchantments" that easily allows you to remove the default Enchantments (and Enchanted Books) for trades offered by Villagers.

Preferred Currency is the currency Villagers will want (default: emeralds) and Offered Currency is what they'll give (default: emeralds). You can now set these to whatever you want. (For example: maybe your server uses a Custom Item as currency? Easily include that to Villagers now!)
