- Added Shift clicking to buy 1 item instead of listed quantity. E.G I sell 16 stone for 1600. If i shift click i will buy 1 stone for 100. - Fixed 1.7.9 dupe (hopefully). - Started enchantment API. - Added a failsafe system.

- If you click a shop and it does nothing in the menu, This means you have messed up on the shop somewhere in the config. Find what shops do and dont work. There should be a point in the menu where they stop working. Find that point then focus on that area in the config for errors. Can be as simple as CAPS are wrong, and dont match the shop in shops.yml or a missing space.
