restored request_lab_test_history function in M::R::ReportUpdate::_do_additional_tests(); DevelCycle only called for dev server (was excluded only for fastcgi); new additional_test.t
new_pnh_alert, juvenile_diagnosis_status_alert & chest_clinic_diagnosis_alert log sucessful emails to request_history; refactored some repeated code in ScriptHelpers
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
