Minor typos in CCphysics classes
CCLightNode - Add to OS X target
Merge remote-tracking branch 'upstream/develop' into develop
CCConfiguration - Print the GLSL version with the other GL info
CCShader - Add raw shader compilation path

Unlike the existing path, the raw does not prefix the supplied source with the
standard headers.
CCShader - Convert built-in shader compilation to use the raw path
Fix whitespace to make it consistent with its surroundings
Converting CCPackageManager's installPath to a relative path.
New path behaviour is relative to the caches folder.
CCPackageInstaller working with relative path.
CCPackage's installURL property renamed to reflect relative nature.
CCPackageCocos2dEnabler working with relative paths now.
CCEffectLighting - Lighting collection fixes

- Don't filter the light list based on distance. I tried this optimization but its causing some
problems so I'm removing it for now.
- Provide an interface for clearing the light collection's group name list. This is mostly just
used for the tests since I want to be able to reset the group names / masks with each test.
- Add a method to CCLightCollection that returns the ambient color sum of all lights matching
a supplied group mask. This is necessary since we want lights to contribute their ambient
color even if they are not in the set of closest K lights that is used by the shader.
