Subject: [PATCH] Bug 18829: Elasticsearch - Put a better display for the view
 of ES indexed record

To test:
- apply the patch
- go to global sysPref
- make sure that SearchEngine have "ElasticSearch" as value
- Search whatever you want in Search the catalog and select a record
- Search the link (Ctrl f) : "Elasticsearch Record :" , click on the link
- make sure that the pop-up open and you should see the elasticsearch result in JSON (the pop-up look the same as MARC preview)
