Reformat SQL queries in such a way that successive "query_story_searches" removal will be more visible
Remove "mediawords_controversy_stats.pl" script altogether because it heavily relies on "query_story_searches" and didn't have much traction since 2013 so is probably not being used
Finish (again) removal of "query_story_searches" by "grep -r"ing the whole codebase for string "query_story_searches" and recursively removing everything related to it
Merge branch 'sql_fixes_20140820-query_story_searches' into sql_fixes_20140820
