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.
