Overgrowth alpha 33

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:

- Preliminary physics editor (video demo) (select objects and press enter to activate them) - Preliminary rigging - Fixed the 'black goo' shader bug - Fixed some Mac editor bugs - Started using Doxygen - Other misc fixes

Here is a screenshot of a physics scene:

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