Updated it so if you have 54 golden apples and you try and buy 64 golden apples it will give you the remaining amount of apples that you need for the right price. I also made it so you can drop items inside of the shop gui.
Added perms for shop. So when you create a shop. It will have perms eg: donutshop.open.shopname. Also fixed a bug with add items. And fixed a few more bugs.
