The refactored tests were written in recognition that Mac and iPhone current working directories are usually not going to work. Resource directories are in bundles and write directories are restricted to certain areas. In theory, other platforms may have this problem too, hence the refactoring.
Also updated the Xcode iPhone project to use 3.2 as the Base SDK, but 3.1 as the Deployment SDK (for iPhone/iPad compatibility.)
