Chipmunk Physics

Would you mind putting include guards in your header files, Scott? At least the chipmunk.h header would benefit from having
at the top of the file and an #endif at the bottom. It's becoming somewhat painful to have to make sure that that header file is included exactly once for any of my source files.

I would like this too - I need to #include chipmunk.h in some of my header files. I would prefer not to have to edit chipmunk.h every time I upgrade.
