I think it is only appropriate that we have Lignite Coal to be added as a valid option for the crafting of Stone Torches.

On a related note we need an alternative Stone from the deeper parts to be able to be made into Stone Rods for the Torches. As it stands right now you can only use regular Stone to make them. If you want to make it a little less common use the Tuff block rather than Deepslate.
