Soul Sand to Sand conversion using Dripstone

To make sand more renewable, add a mechanic similar to the Mud -> Clay conversion using Dripstone.  Place the soul sand over dripstone, and it would drip lava out of the soul sand to eventually convert it to Sand.  Technical players have wanted a better way to farm Sand for quite a while, and this (because Soul Sand is renewable through bartering) would allow interesting farms to be built while not making the process trivial.  Most non-technical players would just go to a desert to harvest sand if needed, so it wouldn't hurt their gameplay in any way, but technical players would have new farms to design and a way to semi-automatically farm sand without using the gravity block duplication glitch.
