* INSERT records about CoreNLP-annotated stories into "processed_stories" instead of "corenlp_annotated_stories";
* Remove mediawords_update_processed_stories.pl background script because now the either the extraction subroutine or the CoreNLP annotator will INSERT into processed_stories directly;
* Add MediaWords::DBI::Stories::mark_as_processed($db, $stories_id) subroutine in order to have a single entry point for INSERTing into "processed_stories"
