Container items display (2.2.0)

• Made the plugin automatically generate configs with the correct enums for different versions as nobody seems to read
• Items that have a container (e.g. shulker boxes) and isn't empty will now show it's contents below the item itself in the inventory view generated when you click an [item] in the chat
• Automatically blocks messages that is way too long and would kick the client (Mainly affects 1.12.2 or below only)
