Title: [bug 781811] Add helpful votes to document index - PART 1 and 2

* Adds document_recent_helpful_votes to mapping for docuement index
* Sort articles by the new field in the IA
* Add cron job to reindex kb nightly

Since this field isn't used anywhere in the current site, we can do everything in Part 1 and just update the READ index in Part 2.
