Blocks using BlockEmbedSnowballLogic. For now, Netherrack (produces embedded netherrack, on fire already), Ladder (runs ladder down to bedrock), Diamond Ore (pit down to bedrock) and Diamond Block (pit down to void).
Not implemented: pressure plate mines. Seems like that is too easy a way to get hold of TNT. I am thinking, the pressure plates could just be placed on dirt as 'decoys' and then if you double glowstone them, that's when you get the TNT mines (wood:1, stone:2, iron:3, gold:vertical stack of TNT down to bedrock)
