    app,util: Move config files from .cache on startup
    
    We just fixed the regression of Boxes keeping configuration files under
    ~/.cache rather than ~/.config but since this regression has existed for a
    long time now, many users would have their configurations under ~/.cache
    now so we need to ensure the configuration gets moved under ~/.config.
