    dnd: Fix syntax error which led into g-s not starting anymore
    
    With the recent port to JS6 classes, the trailing
    comma after functions in the syntax of classes has
    been removed.
    However commit c2961f21 accidentally reintroduces
    one trailing comma after a newly created function,
    leading into g-s throwing an exception and not
    starting anymore.
    
    Therefore, remove this trailing comma to solve
    this problem.
