Here's a new update!!!

Fix - Now you can use the anvil with books or items under the vanilla limit without permissions.
Add - New permission anvilenhanced.enchant.use-books to use books to enchant an item without the possibility to increase enchantment levels.
Change - Now you can use any permissions plugins. I now use Vault to check permissions. Obviously, Vault is now a dependency to use AnvilEnhanced.
Change - I changed a lot of conditions. Now it's more logical the way levels are handle if the level is over the config limit or just over the vanilla limit.
Change - New update checker for my plugin. You'll see a message in the console AND in game if you're OP.
Change - The default.yml and all others .yml files for every rank are in their own sub folder "Ranks". Once you restart the server, just move the files you already created in that folder.
Change - The reload command is now /aereload.

And some code cleaning...
