Aenv 286

- [x] - AENV-286 - Make the AES plugin aware of the article language and publication object. Provide the proper API enhancements to provide that info to the AES.

Will add `publication` and `languageData` data into article API:

```
...
   "languageData":{
        "id":1,
        "name":"English",
        "code":"en",
        "RFC3066bis":"en-US"
   },
   "publication":{
        "id":2,
        "name":"The New Custodian"
    },
...
```
