Reference local images in Xcode project

There was a sneaky problem in Jenkins where skin assets were being pulled from the wrong folder. The SD app was showing LA's default tree image. The root of the problem appears to be that the project file referenced a symlink path rather than a local path.

I removed the images folder from the project, copied one of the skin image folder into the local project path, and then added the images back into the project. In my local testing, I could now successfully replace the real directory with a symlink and the images would correctly change inside of Xcode.
