Sulfur Slime Balls and Blocks

Sulfur Cubes should drop sulfur slime balls, which can also be crafted with 1 slime ball and 1 sulfur. Sulfur slime balls should be crafted into sulfur slime blocks which can consume blocks. When it has a block inside it, it can only stick to that specific block. This will be useful for machines that can't have obsidian or any un-stickable block for some reason.
