Subject: Make PictureViewer2 size configurable

Several bug fixes on the way:
* set fixed size policy for PictureViewer2 -> makes resizing much easier
* don't set Y-offset when showing a pic. The scene takes care of it
* don't deliver SIGNAL configChanged() twice to PictureViewer2
* center Widget on current screen when calling Helper::centerWidget
