removed all BEGIN blocks from cron scripts - need to load Data::Dumper's Carp from local::lib before system Carp gets any chance of loading

split outreach charts into 2 to accomodate CML outreach; added better date handling routine for charts; changed auto-screening handling of specimen code for CML outreach requests; bugfixes to HMRN to remove legacy 'chronologies' table entries; removed redundant code/queries for error_codes.pl script

enabled weekly crons

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

bugfixes to error_code_assignment updates; redefined date_format() to date() for library.sql entries with standard %Y-%m-%d format
