Refactored automated rwops tests so read and write directories can be more easily customized. 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.)

5 /* For proper OS X applications, the resources are contained inside the application bundle.
6 So the strategy is to first check the application bundle for the file, then fallback to the current working directory.
7 Note: One additional corner-case is if the resource is in a framework's resource bundle instead of the app.
8 We might want to use bundle identifiers, e.g. org.libsdl.sdl to get the bundle for the framework,
9 but we would somehow need to know what the bundle identifiers we need to search are.
10 Conversely, write directories are usually not in the bundles. This implementation uses NSTemporaryDirectory,
11 but consider Preferences, Application Support, Documents, etc.
12 Also, note the bundle layouts are different for iPhone and Mac.
