RfC450 - incomplete requests function * move clinical trials from screening term to separate section * move queries to SQL::Abstract (request_ids query needed 2 multi-placeholders)

new home page (hello) link and quick search function on 'hello' page for non-lab-staff users; added optional sort_by to M::LabTest::get_section_lab_tests; added optional command-line arg to nycris.pl

modified method of determining whether C::Worklist::display() is for data entry and how return is handled; incomplete_requests have date stamp; awaiting_final_diagnosis list includes diagnosis = awaiting final review

moved incomplete_requests sql out into library.sql; removed time from incomplete_requests date fields

incomplete_requests.pl split into separate emails per reporter; bugfix to hmrn demographics, broken by previous outreach demographics change

logic to determine whether to set request status to complete considers result summary datetime relative to authorisation datetime; replaced io unlink() with system unlink in render_pdf - was giving occasional errors; replaced M::Base::does_authorisation method with Moose attr to save repeat db queries; fixed oversight in _archive_report_details() causing history log to record amended specimen_date at every authorisation; gallium_data.pl checks for comment field to prevent fatal error; more report_status.t tests to test for status change on delayed result summary entry

incomplete_requests script includes reporter/authorisor info; new_national_code script patched to skip instances of requests where new referrer registered then amended on same day
