    editor: bring back "Reveal in Project Tree"
    
    Disabled this during the plugins extraction work, can bring it back now
    and move the helper to GbWorkbench.
    
    Long term, I'd like to figure out a clean way to move the project tree to
    plugins, which will complicate this a bit. However, once we have a
    GbEditorViewAddin (or whatever better naming we come up with), the
    project-tree could provide this feature itself.
