message:
  Removing InputDispatcherConfiguration and the by-pass of the InputTranslator using a dynamic cast that was only necessary until lp~andreas-pokorny:extended-input-dispatcher lands

  The contents of the former InputDispatcherConfiguration have been moved to DefaultServerConfiguration. En passent the nested input relay was dropped too. The mir::input::InputDispatcher interface is now used directly. Note: Event filtering still works like before.
