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.
