Got the app hiding in the system tray, though icon isn't working.

When you hit the close button on the window, it hides in the system
tray, or when you hit File>Hide or Ctrl+H while the application has
focus.  I have some testing code in to see why the icon isn't being set,
but still can't figure it out.  The icon is definitely loading, it's
just when I set it to the icon it's no visible.  I'm even not getting
console output saying no icon is being set.
