Changed handling of crafting to allow for ItemStack larger than 1 item to be crafted without using the item duplicating it
Also, in the process re-added permissions, they're all lowercase for ease of use, sorry they were ever case sensitive, they are as follows:

• bandage.craft
• medkit.craft
• bandage.use
• medkit.use

I suggest resetting your config if you have any issues
Should fix issue #1
