Dispensers should place Pointed Dripstone, and other related ideas

It'd be cool if Dispensers could place Pointed Dripstone, especially if it could automatically extend a stalactite/stalagmite. Being able to build stuff like retractable spike pits and automatically resetting falling Dripstone traps would be incredible for Adventure maps! It could even work as a way to toggle on/off lava farms if for whatever reason you wished to do such a thing. Might also be fun to allow Pointed Dripstone to be placed sideways to form spiky walls that the player won't want to touch, and even allow sticky pistons to push and pull them. All sorts of skewering scenarios could be made with these additions!
