moved trials list out of trial_cases.pl into settings.cfg; outreach tt bugfix; added chart link to report tt so chart displayed in normal view - no need to generated printed report
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
