This creates a class goAppDelegate that will be used as the delegate for /everything/. Specifically, it:
- handles window close events (windowShouldClose:)
- handles window resize events (windowDidResize:)
- handles button click events (buttonClicked:)
- handles the application-global Quit event (such as from the Dock) (applicationShouldTerminate)
