perl 5.14 issues: skipped Devel::Cycle for test suite until 'Unhandled type: REGEXP' warning fixed; can't call 'uc' or 'lc' on missing query param; molecular worklist tweaks
patched C::Search::do_search() & M::Request::get_request_id() to capture undef request_id error - occured when request_specimen entry was empty (should be impossible)
HMRN new diagnoses list displays number of previous requests for patient; multiple record search displays request and diagnosis status, with diagnosis as mouse-over if authorised
