Fixed an on-exit crash for apps using GL.
If a QGLWidget is left on the heap when the QApplication destructor is
called, it will leave the QGLWidget in a broken state.
The widget itself is released and set to a non-created state,
which the associated QGLContext doesn't get notified about.
With this patch the QGLWidget knows when QWidget::destroy() is called
and can act acordingly.
Task-number: QT-3498, QTBUG-10995
