    Make Ctrl-Mouse open an included file for editing.
    
    It might be nice to do this also for other insets that allow editing.
    To do that properly, we'd want to standardize how such insets call an
    external (or internal) program, which I guess would mean a virtual
    method corresponding to editIncluded. When it exists (i.e., isn't null),
    then we could call it, and we'd only need one centralized method to do
    that. But at the moment, we have editGraphics, etc.
