Sponge bug.

@CovertJaguar Apparently sponge doesn't want our inventory to implement iterable for something other than Iterable<org.spongepowered.api.item.inventory.Inventory>. Blame Mumfrey.

They make a change like that and expect it to break nothing? Lol.

Closing due to _Not Railcraft_

I think I will start working on the sponge compat soon, at least fixing this thing
