Title: Add Pipe Content ItemStack NBT sync.

This allows to sync the NBT tag information stored inside the ItemStack. Should fix some rendering bugs where the renderer depends on data stored inside the NBTTagCompound tag of an ItemStack.
Through the handshake Packet way this shouldn't increase the bandwide usage and ensure the NBT tag information where needed.
