Added initial port of original OSX project.

- This is a copy of the [OSX](https://github.com/bkuhlmann/osx) project
  originally released on 2012-03-31. The OSX project has been
  deprecated. All future development and support will take place with
  this project instead.
- This project uses the *macOS* name in order to better match the
  updated branding and terminology used by Apple.
