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
