Blue Menu

- The sync-menus section in settings.yml now supports "*" in send and receive so you don't have to register menus manually. - Added experimental support for custom Java menu items from Nexo, Oraxen, and ItemsAdder. You can now reference provider items either with itemStack.provider + itemStack.id or with prefixed itemStack.material (for example: nexo:item_id, oraxen:item_id, itemsadder:namespace:item). If a provider plugin is not installed/enabled, BlueMenu safely falls back to standard Bukkit material handling. Example: ```yaml items: custom_sword: name: "<green>Custom Sword" slot: 11 itemStack: provider: nexo id: ruby_sword amount: 1 lore: - "<gray>Provided by Nexo" custom_gem: name: "<aqua>Custom Gem" slot: 12 itemStack: material: "itemsadder:my_pack:gem_blue" amount: 2 lore: - "<gray>Provided by ItemsAdder"```
