minor re-arrangement in M::Result::get_section_lab_test_results(); switched new_referral_source and new_referrers scripts JUST_TESTING flag on and switched new_national_code JUST_TESTING off
incomplete_requests.pl sets request status to complete for any requests with status = authorised and no outstanding tests and not requiring diagnosis confirmation; new daily new_referral_sources.pl cron
outreach charts don't plot unless 2 or more datasets; added find GP by practice function to outreach demographics; set permissions mode on all crons so svk revert on production doesn't revert to 644; set results summary to default open on report page - correctly this time
more patches to cron scripts - all date subtractions performed on a new time_now() object in ScriptHelpers::date_subtract(), NOT on the local object in case it's used again after the DT subtract() function performed
amended all cron scripts which used DateTime directly to use L::Local::Utils::time_now() instead, so time calculated correctly at day rollover (ie considers BST); patched Utils::time_now() to accept args for DT constructor (eg formatter)
