Inventory Manager should bind player directly to the block instead of using memory card

[zyxkad]

Describe your idea (If you have more than one idea, please open the rest in other issues)

Since people can steal others memory card and dump others inventory continuously, which make other people unplayable, we should change how inventory managers identify their owner.

One idea is completely get rid of memory card, and save player NBT in the inventory manager when someone placed it. Another idea is when the memory card takes out (or when insert) it becomes a clean one.

I would prefer the second idea for 0.7 And a rewrite of the inventory manager logic for 0.8 with multiple memory card support
