Bindings generator: Problem with QMenu::addAction() (prototype shadowing)

addAction(QAction*) is defined in QWidget; however, QMenu introduces new overloads for addAction(). The generated implementation of QMenu.prototype.addAction currently doesn't generate a binding to QWidget::addAction(), which means that calling addAction() with a QAction as argument is impossible (QWidget.prototype.addAction is effectively "unreachable").
