Almost entirely functional silent shulker boxes

For whatever reason, the shulker box EnumDirection isn't being retrieved properly, so AnyChest will only trigger on shulker boxes that would not be able to open if placed downwards (opening upwards). Silentchest and anychest will work, though.
Suppressed a few deprecation warnings that don't make sense to keep.
If you do use my fork of OpenInv's API, it's not yet stable (specifically, IAnySilentContainer), and will change a little more as I polish things up.
