Add a Cocoa UI for the updater on Mac

* Link the updater application with the Cocoa framework on Mac

 * Construct a UI in code and display it when running the main install process.

   Usually UIs on Mac are contained in a .nib file created with Interface Builder
   but in this case the UI is created directly in code to meet the single-binary requirement,
   although it may be possible to bundle the .nib into the binary itself.
