Major Update: ItemSkins Overhaul & Seamless Integration!

This update brings groundbreaking changes that we've all been waiting for!

ItemSkins now fully replaces the item while preserving NBT data – ensuring a smooth experience.
Full compatibility with Nexo and ItemsAdder – simply insert the item ID from Nexo or ItemsAdder for effortless integration.

Important: This update is still experimental. Some plugins that modify item creation may have issues. One known conflict is with the Prison Core pickaxes plugin.
