Place 1.8 stones! 1.7 clients will see regular stone, while 1.8 clients will see the new stones. I will add crafting recipes tomorrow, but I'm too tired now.
/bs <get|give [player]> <item> [amount]
In order to spawn the new items, players need the permission bountifulstones.spawn
If a block is broken, it will drop cobblestone. I may work on this tomorrow, too. This is likely not useful, but it's out there for anyone who might want it.
