    about dialog: Don't hardcode the recipe authors
    
    We can get this information from the recipe database.
    Doing so is a small step towards decoupling the recipe
    and chef data from the application, so they can eventually
    be updated independently.
    
    Since the list returned from the database is unordered,
    we now sort the list of recipe contributors alphabetically.
