RsPrettyJson only support json objects #1299

If one returns a JSON Array and try to pretty print it there is an error:

java.io.IOException: javax.json.stream.JsonParsingException: JsonParser#getObject() or JsonParser#getObjectStream() is valid only for START_OBJECT parser state. But current parser state is START_ARRAY

beside that it would be useful if one can pass directly a JsonStructure to avoid the additional parsing of the body.
