Overgrowth alpha 47

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!

On the coding front, here are a few highlights from the source repository:

- Initial localization system - Added UI for creating constrained hinge joints and ball joints - Added loading and saving of skeletons - New character model - Added automatic point size adjustment for small bones - Fixed greenhills level - Character tweaks - Bug fixes

Rigging improvements

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