Disabled movement of dock widges, unless in "Advanced Mode" (File->Advanced Mode)
Addition of new "view" based navigation, and moved DockWidgets inside each
view, rather than having universal dock widgets.
Changes for the new "View" navigation, and fixes to get most of the dockwidgets working with the new view system
Additions for View navigation, including saving dockwidget locations and status. Also added remembering of "Advanced Mode" between restarts of QGC
