Package needs update to implement new V2 API specification

[marrouchi]

New parse payload have the following data structure :

{"text":"Bonjour","intents":[{"id":"467958847129146","name":"greeting","confidence":0.9986}],"entities":{},"traits":{"language":[{"id":"0596e762-b648-4e55-84ff-2fbaa4eca22b","value":"fr","confidence":0.9989}]}}

I don't know how much it will impact the current code. We must review the full API documentation.

@bashz i would recommend tagging the current branch before
