Floating Sulfur Cube

I think the sulfur cube need an archetype that make it float.

While this archetype is used, the cube would float in the air at a maximum height (e.g. max 50 block above the ground/liquid) and extremely hard to put in water.

Using the descriptions in the changelog it could be:

Float: high speed, high bounciness, no ground friction and low air drag.

If a Floating cube is smashed upward out of it's max block height, it looses it's floaty ability and fall.

When a Floating cube fall back below it's max block height, it's velocity decrease until it's stabilized, according to the air drag.
