Overgrowth alpha 48

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!

Here are a few highlights from the source repository:

- New wolf model - Added fixed joints - Fixed saving bug - Added CPU skinning - Disabled baked lighting for characters - New plant shadows and lighting - Fixed mac mouse buttons - Improved keypress consumption - Improved ball joint constraints - Created and hooked up ball joint UI - Bug fixes

Voxelizing the new wolf model for the upcoming automatic vertex weights feature

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