[LyX/master] Add override statements to please clang

[Jean-Marc Lasgouttes]

commit c8f4b68423520378d02fe9f953d94759b862dc55

    Add override statements to please clang
    
    Eventually, all overridden virtual methods should be marked properly.
    Currently, clang only warns about those in classes that already use
    override in at least one place (which was the case dor GuiApplication).
