[tests][tutorials]#134: Refactor working path utility to allow working path to be changed to resources directory.

Resources directory will be different depending on platform. This is test/tutorial specific, and not related to Indielib.
Desktop win, linux:
- Assuming relative path ../../resources to mirror repository

Desktop OSX (Bundled) and iOS:
- Inside the app bundle, meaning <Bundlepath>/resources

Added a copy files action for iOS and OSX to copy resources directory to bundle.
