bridge.get_ranked_posts is hard-coding 'is_pinned' to False for every post (development branches)

bridge.get_ranked_posts returns the posts in the correct order with the pinned post first, but the stats for that post say is_pinned: False

This appears to be happening in the process_query_results section: post = append_statistics_to_post(post, row, False, blacklists_for_user)

The 3rd parameter to the append_statistics_to_post method is the 'is_pinned' field, which is currently hard-coded to always be false, so the condenser isn't properly marking a post as pinned on the front end.
