CMake updates:

1. Initial compatibility with CMake 2.6 (verified on Mac OS X, other platforms may need more work)
2. Ability to more easily debug problems fetching prebuilt libraries (./develop.py configure -DDEBUG_PREBUILT=1)
3. Compatibility with Mac OS X MacPorts/Fink installations by trying to find and use system python executable first
