Overgrowth alpha 35

Here is what is new in Overgrowth in this weekly alpha. If you are confused what a weekly alpha is, or even what Overgrowth is, please read our fancy FAQ. Basically, we are developing a massive video game from the ground up -- we are able to do this completely independently by accepting preorders for the game before it's done!

Aubrey has made a number of new art assets this week. On the coding front, here are a few highlights from the source repository:

- Improved sky editor - Fixed a number of grouping bugs - Sun loading and saving - Sun color affects lens flare - Added live sky texture update - Reduced memory usage - Fixed lighting on rabbot and physics objects - Modular shaders - Bug fixes

Thanks as always for all the support! See you guys in IRC and the forums.
