Commit d687d112 unfortunately caused
two severe regressions for MeeGo:

QTCREATORBUG-6473: The application creates two QDeclarativeViews
QTCREATORBUG-6490: QDView functions inaccessible. Existing apps broken

This commit removes most of d687d112


just leaving the boosted QApplication. Now, QmlApplicationViewer *is*
again the QDeclarativeView.
