added format_firstname callback in templates to enable user-configurable special formatting to first_name - uses format_first_name sub in render_view + format_firstname.yml; changed user_location.region_code to varchar(5) to allow longer parent organisation codes
moved authen_config from lims_config.pl to main LIMS app - CUSTOM callback doesn't work when cfg loaded using Class::Singleton instance; modified idle timeout function to automatically load logged-in username in login screen, so only passwd required, and added link to logout if different user; cgiapp_prerun checks form param username matches authen; added region_code back to user_locations + admin functions
