    /** Callback function for changes in the dev mode that affect debug levels.
        The function behaves according to these rules:
        - 'normal' mode is defined based on where the program was launched: if
          the launch path was the build directory, development mode \c on is
          normal, otherwise normal means development mode \c off.
        - Debug levels should not be hard configured (\c config instead of
          \c tconfig) in non 'normal' mode to avoid strange behaviour.
        - Changing the development mode from 'normal' to the other state will
          immediately change the debug levels to predefined values which can be
          reconfigured with \c tconfig.
    @note
        The debug levels for the IOConsole and the InGameConsole can be found
        in the Shell class. The same rules apply.
