- Use modern string literals (use QStringLiteral instead of QLatin1StringView for strings that go into the DOM API). - Use mime types in the file dialog handling - Streamline code - Remove mentions of SAX - Use per class includes - Do not use QObject::tr() - Use the configure system instead of QT_NO... defines - Fix some doc text typos Complements 3dd3268ded4dd74c64d7ec726fd534375ab9f018.
