Multi Language support

Overleaf can support multiple languages per container. This is done via different domains configured to respond in a set language using the env variable OVERLEAF_LANG_DOMAIN_MAPPING (or SHARELATEX_LANG_DOMAIN_MAPPING for versions 4.x and earlier) with an escaped JSON string.

OVERLEAF_LANG_DOMAIN_MAPPING = '
    {
      "www": {
        "lngCode": "en",
        "url": "http:\/\/www.mysite.com"
      },
      "fr": {
        "lngCode": "fr",
        "url": "http:\/\/fr.mysite.com"
      },
      "de": {
        "lngCode": "de",
