Sticky Piston Sulfur Cube

Something I've noticed with the new Sulfur cube is that when pushed by a sticky piston, it acts the same as if it had been hit by a player, rather than sticking to the piston like a block. I think we should keep regular pistons the same as a player hit, but sticky pistons should stick to the cube. This would be great since they are entities but would behave like a normal block.
