Polish the examples/widgets/dockwidgets example.

- Introduce Qt 5 signals & slot syntax.
- Use QIcon::fromTheme() to obtain system icons and use
  resource icons as fallback.
- Fix minor issues in code, use multi-argument version
  of QString::arg(), QDir::toNativeSeparators() to
  present file paths to the user, static method
  invocations.
- Use QMimeDatabase for file dialog.
