add "json" method into the JsUtils

[GoogleCodeExporter]

wiQuery uses the jackson api for the autocomplete component. Maybe we can offer 
some methods to generate json.

jackson is best used using annotations and the ObjectMapper. See

Of course, I mean generate some json with jackson (not with our own methods)

Fixed in r719

Just a little method:

/**
     * Method using the jackson API to generate a json representation of your
     * Java object
     * @param jsonObject A serializable object
     * @return the json representation as a string
     * @throws IOException Exeption during the process
     */
    public static String json(Serializable jsonObject) throws IOException {
        StringWriter sw = new StringWriter();
        JsonGenerator gen = new JsonFactory().createJsonGenerator(sw);
        new ObjectMapper().writeValue(gen, jsonObject);
        return sw.toString();
    }
