Qt4 - Resizing changes. Part 1
Remove the QDockWidget, this widget is clearly not what we want, since it is a Qt::Tool and stay above the video, it doesn't want to grow in the MI and it doesn't record correctly its size. Moreover, this force the GNOME/Cleanlooks hack that is boring on Xfce, KDE4 and e17. Fix the resize when the video is done. Fix the qt-start-minimize bug Rename a few functions and separate the code functions. Simplify a few resize/update call.
