by CovertJaguarMerged EntityData and EntityPassiveItem
They have been replaced by TravelingItem. Which means yes, I broke the
various pipe hooks again.
Additionally IPipedItem and IEntityPassiveItemContribution have been
deleted. Contributions were replaced by a simple NBTCompoundTag field in
TravelingItem (which is essentially all that contributions were anyway).
