Player movement should affect the speed a sulfur cube gains from a hit

If a player moves forward (the direction they are facing) in a horizontal plane when hitting a sulfur cube, the cube should gain more horizontal velocity from the hit. Moving backward should reduce the horizontal velocity the hit gives to the cube.

The same should apply to vertical player movement which would affect the vertical velocity of a sulfur cube. So if you jump and then hit the cube, it would fly higher, but hitting it while falling would make it fly lower.

This change would allow players to adjust the sulfur cube launch speed without having to switch items. Mini game creators will be able to immobilize players using mounts, blocks or potions if necessary.
