Add setJSONParser, setJSONConfig to provide database object global JSON configuration. All methods internally now use the default JSON generators and parsers if no JSONParser is given. The code stops manipulating incoming JSONParsers but only works on configuration copies of JSONParsers which is much safer etc.
