Unique

I have seen a lot of people wanting to have custom beds... so... why dont we had this new feature:

- Beds can now be edited with banners, making you have your own bed design, just like shields.

Also people want Elytra with chestplate so how about we do this:

- New slot in inventory, like the offhand, but its the back, so you can put elytra and also banners in case you want to do a world with your friends where you have clans.
