Config file

• Added ability to configure whether players in creative mode are affected by the inventory freeze / inventory locking functionality.

Locked inventory slots visual indicator rewrite

• The locked inventory slots visual indicator has been entirely rewritten from scratch.

• Fixed an issue where many resource packs and mods that modify the inventory would prevent the visual indicator from displaying.
