[json-glib] Doubles are converted to strings containing commas

    Doubles are converted to strings containing commas
    
    Under some locales (e.g. de_DE) a double is converted to a string
    containing a comma instead of a dot. That breaks the JSON syntax.
    
    Example:
    Double: 0.34 is converted to 0,34 when using locale de_DE
