2.0.0 Pre-Release 2

This release fixes some bugs and adds a helper interface for permission abstraction

• A PermissionHolder interface was added
  • This interface contains functions for checking player permissions or operator levels
  • This is inherited by both ServerPlayer and CommandSourceStack on Fabric servers
  • A CommandPermissionHolder class was added to Spigot servers which can be used to wrap CommandSender objects.
• A few Spigot-related bugs have been fixed since the last pre-release:
  • Spigot Inventory GUIs now properly show titles
  • Spigot servers running 1.20.2 no longer throw errors when attempting to update player skins
  • Modern Spigot servers (1.17+) no longer throw errors when applying NBT to items
