• Fix bug that would cause EP to individually sync each post during an import - disabled syncing during import - requires a full re-index after import

• Add filter to allow adjusting which fields are searched (ep_search_fields)

Minor adjustments including fuzzy default to .75 and some hooks/filters.

Now requires WP-CLI and an EP_HOST constant for the connection URL to your Elasticsearch application.
