Brush up the main window examples

- Use snake case in dockwidgets and application.
- Fix imports in application to be consistent with others.
- Fix the code saving/restoring geometries in mdi/application
  to use QWidget.save/restoreGeometry() instead of saving pos/size
  since that handles multiscreen setups correctly. Use 'QtProject'
  as settings category.
- Use theme icons in application as in mdi.
- Configure QFileDialog for saving HTML in dockwidgets.
- Replace QSignalMapper by partial functions in mdi.
- Fix one oversight of 4f2f9e2dc511ddcf802e342361e89edbf03a4a88
  in mdi.
- Add command line arguments
