Desktop: Derive UserManual from QDialog

Browse source 
In commit d21d42b691 helpView was made
a child-object of MainWindow, which is Qt's idiomatic way of having
helpView deleted with MainWindow.

As an unintended consequence, the helpView didn't show. The reason
is that UserManual derives directly from QObject. In contrast, UserSurvey
derives from QDialog and is correctly shown. Therefore also derive
UserManual from QDialog.
