Added a new nebula system. This is my second attempt and looks a lot better then the first.
Still needs a little polish (need some color variance in the clouds). I think in the end I'll need to combine this with the first approach (which was basically a set of shells that had increasing transparency). Doing a large area with the billboard clouds will be too fill intensive (this example is 800 billboards). So I'm thinking the final solution will be the shell with billboards along the edge.
Plus, I need to finally add to my general pixel shader to fade out at a distance so I can bring it in and color it when you are inside a nebula.
