minor tweaks to bring test suite up to date with recent changes

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

bugfixes to allow test suite to pass

added ability to restrict non-network users to own records; added missing _debug_path() to controller methods

minor bugfixes & tweaks

added resultsummaryoptions.html help file; changed optgroup and numerical order flags on result summary menu options; fixed error in lims.sql

new user message alert ajax function - might be causing loss of html_wrapper until next server restart

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

added new region_code col to user_locations table; updated admin user_location function + validation to reflect

added a user messaging system; user change registered email resource

moved login.tt from site to login/default.tt; used authen->is_new_login to redirect to C::Login::hello(); moved code to generate new diagnosis list from LIMS::_create_user_profile() to C::Login::hello(); new db table user_message + DB class

new user application form

replaced several calls to L::Local::find_home() with call to config instance; removed call to L::Local::Debug from lims_config.pl, as debug() uses config instance, which uses lims_config.pl; model classes get config from config instance instead of constructor passing it in LIMS::model(); general tidy-up

bugfixes to bring test suite up to date - all tests (2857) pass
