Sulfur Cube

In the latest beta, the Sulfur Cube can absorb some blocks and change its physics. I really enjoy this mechanic. I suggest adding these features: 1. Allow Sulfur Cube to absorb TNT blocks. ​ 2. When it absorbs TNT and is squeezed by pistons, falls from high places, or under heavy pressure, it explodes like a TNT minecart. ​ 3. The explosion power can be slightly weaker than normal TNT for balance.
