completed task to allow merge of patients without attached requests; extended patient_merge.t to test for orphaned patient merge

bugfix: model methods do_specimen_code_update() and new_request() delay do_specimen_associated_lab_tests() until after new specimens loop to avoid problem with Moose attr request_specimen_sample_type() loading only once - for 1st specimen type

replaced loading of Local::DBIxSimple in individual model classes with single loading in Model::Base; renamed DBIxSimple::get_meta to dbix_get_meta to avoid clash with Model::Base::get_meta (now renamed get_meta_data); fixed report.t - new method report_diff replaced comment

configured request registration to auto-increment request number (for Cambridge); patched tests to work with auto-incrementing lab number flag

specimen date editable in request_edit; FormValidator::Simple date validation switched to datetime to handle specimen date

added request_specimen_detail table to get_single_request() method for displaying specimen_taken date on tt view, as request_report_view requires request to have been reported

added datetime specimen taken to registration and print_view pages; removed CPA icon from report display (interferes with messaging lionks); changed colours on additional comments display

removed request_gross_description from app; added request_secondary_diagnosis definition; replaced underscores with spaces in history display; morphology and comment optional displays in request summary view; more tests in report.t

update report function now logs edits to all report fields; fixed all broken tests so far

refactored request_report table again - replaced 'vertical' request_specimen_detail and request_report_detail tables with conventional 1-2-1 mapping with request table

interim report refactor commit

external user login far too slow due to previous diagnosis list query - separated into 2 queries and created request_status_view - much faster now

histology block refs displayed in year groups; changed date ref to 16 char string for recorded delivery info; returned list of records updated instead of redirect to redisplay block ref worklist

bugfix to outreach/demographics.tt - patient_id => patient.id; minor tweaks to get_request_id_from_lab_number()

replaced M::Request::get_request_from_lab_number() method using multiple db lookups with get_request_id_from_lab_number() using single db lookup
