Overgrowth alpha 49

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:

- Added new automatic vertex weights - Made it possible to exit rigging tool - Improved skeleton saving and loading - Added initial animation editor - Added Catmull-Rom keyframe interpolation - Fixed bone-link cursor - Added alt-dragging in animation editor - Ribbon improvements - Added several new cursors - Removed maximum bone limit - Bug fixes
