New Lighting Options for Noise Caves

I played the most recent snapshot in hardcore to get a feeling for it. And while I love the new cave generations and they're awesome. I do think we need better ways to light them up. At the moment they are huge and dark and I use a lot of coal just to light up one section to make it safe. What I suggest is adding a new item/items that are accessible to early game cavers that makes lighting up the noise caves a lot easier. While i'm not creative enough to come up with specific ideas, I think new, easy, cheap lighting items would greatly benefit the introduction of noise caves.
