    Add more checks to make the controlport auto config better
    
    It checks if DataDirectory is empty, and disables the feature in such case.
    It also checks the tor version and doesn't let the user save the
    configuration if she hasn't added a DataDirectory when "Configure
    ControlPort automatically" is checked.
