Dripstone Dries Wet Sponges

Wet sponges, when placed on a block with a pointed dripstone underneath, should have a random chance to become a dry sponge on random gameticks.

This mechanic has already been established with the dripstone method for converting mud into clay. This would not replace the normal drying method using a furnace, but would allow for more ability to automate the placing and removal of water source blocks in redstone contraptions, such as a hidden waterfall door.
