Polish the XML bookmarks examples

- Use Qt 5 connect syntax.
- Streamline code, remove unused members.
- Add a context menu for copying and opening the URLs.
- Add const to XML code.
- In the XML code, show the use of QStringLiteral in static inline
  functions to create strings versus QLatin1String in comparison
  overloads to avoid allocating strings from const char * literals.
