- Introduce Qt 5 signals & slot syntax and remove the QSignalMapper used to map the triggered() signals of the per-MDI-child actions of the window menu to the activation slot by a functor to demonstrate the flexibility of the new connection syntax (the functor can in turn be replaced by a lambda expression once we have C++ 11). - Merge MainWindow::createMenus()/createQToolBars() into MainWindow::createActions(), removing the need to store the actions as member variables. Use QMenu::addAction() for brevity. - Use QIcon::fromTheme() to obtain system icons and use resource icons as fallback. - Rewrite settings code to use QWidget::saveGeometry(), Widget::restoreGeometry() since saving size and position does not work well with multiple screens. Query the available size when determining the initial size instead of using hard-coded values for High-DPI screens. - Fix minor issues in code, use multi-argument version of QString::arg(), QDir::toNativeSeparators() to present file paths to the user and static method invocation.
