Polish the settings editor example.

- Set QtProject as organization.
- Remove unneeded member variables.
- Use member initialization in the constructor.
- Use new connection syntax in createActions()
  to assemble the menu there, removing the createMenus()
  function.
- Introduce a QSharedPointer to ensure settings are deleted.
  Previously, the settings were parented on the tree widget,
  which is a hack of sorts.
- Fix OS X macros.
