I have tidied up a bit, and added another dependency, ArmorEquipEvent.
This means you will need to install this in your plugins folder, this is the link to the jar

Thanks to ArmorEquipEvent Wearables will also do a better job at detecting disguises being equip!

updated api version so some compatibility may fall off in this version if you are running 1.13.X or lower and have trouble try the latest 3.X release in the versions section.
