corrected mistake made in v1464 which switched off query logging in production mode; minor edits to new_referral_source.pl

amended new_referral_source.pl to examine request_history for changes to referral location to catch new locations 1st used when date of amendment != registration; patched activity_data script to use a branch-to-parent-practice map

modified Outreach permissions to allow reporter to access data; modified Hodgkin notification cron to send message even if no new cases

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
