modelizer: Minor update to feature keyness, using absolute values now to determine the most informative features for a class (so features that are either strongly postively or negatively related to the class)
bulk_writer: Added the 'ver' parameter to include a short version string with each update. Mostly to deal with updates that do not complete successfully on all data
query_gen_actors: Added an additional generator for the "Institution" type (for EU support)
actorizer: Created an updater function to search for actors and use UDPipe to parse the results
