New hopper mechanic

I suggest that when an item is moving upwards and hits a hopper, the hopper would "absorb it" for a moment and then launches the item 1,5~ up. The reason why I suggest this is because it could be a way making """upside down hoppers""" without pipes or complex stuff that doesn't really fit in minecraft. Also, a hopper which launches an item into another hopper would basically do the same as the other one until the hopper chain's over, so that the item doesn't just get in the same hopper again after landing.
