You can now require a player has a permission to use a recipe! Just set "permission" under the recipe, and the player will only be able to craft that recipe if they have the permission.
All permissions are prefixed with "customitems.recipe.", so if you set "permission" to "magicStick", the user will need the permission "customitems.recipe.magicStick" to use the recipe!
In addition, this update makes some minor bug fixes with matching native Minecraft materials
