Leaves can gather water!

In the desert we all know every leaf block in minecraft are kind of brown and poopy looking, so if you can have a water source block near the leaves then they can get water from that, making them green! This would be a great idea in my opinion as I was watching Keralis and seeing him working with leaves. In which, gave me the idea so we could add some more leaves besides spruce leaves to our builds in the desert :D
