Overgrowth alpha 46

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:

- More progress on the rigging editor - Initial resolution independent UI - Some new cursors for rigging - X-ray editor widgets - Connection rigging - Animation editor UI - Better UI anti-aliasing - Fixed ctrl-g beep - Initial automatic vertex weights - Vertex shader skinning - Bug fixes
