commented out redundant outreach relationship in DB::Request; replaced night sweats select option with radio button in outreach questionnaire; replaced other repeating blocks with FOREACH list in outreach questionnaire templates
fixed ajax error on NHS number validation when length exceeded 10 chars - fatal error due to RDBO patch; extensive changes to outreach questionnaire section to accomodate new questionnaire and CML patients
bugfixes - cannot use DateTime->now default in DB::Request for new request as DB classes loaded once so new request fails on turn of year unless server restarted; activity data requests without referral source list trial name if exists
