Implement custom fish worklist driven by templates

Add warning when requesting label of sample type that isn't meant to print

working validation on some result data types; TODO: fix many broken tests

storage vialId validation - dissallow '/' (breaks url for edit function)

Genomics - prevent duplicate patient-request submission using back-button

validate secondary diagnosis to prevent duplication of primary diagnosis * leads to loss of duplicate diagnosis data on rendering of Rose object by template or as_tree() * rename ConstraintMethods 'check_eq_with' to 'check_vial_id' for consistency with 'check_secondary_diagnosis' validation method

move lab-test accreditation info from yaml file to database; admin interface to lab-test accreditation; remove flash message about ukas_accredited_tests.yml after new lab-test, replace with redirect if appropriate

bugfix - incorrect message format causing 'Odd number of elements in anonymous hash' warning

RfC336L - unaccredited tests - replace report url link with list of named tests from yaml file

bugfix - flash messages set in C::L::Labels don't appear in tt * fixed by handing calling object (C::L::Worklist) to C::L::Labels for setting flash messages on * factored CAP::MessageStack rendering block into its own snippet tt for calling independently from site/status.tt * bugfix to 2 test scripts

fix 500 http error when user selects print labels for 0 labels

fix for error 5954b76b7745 - "no id passed to password_reset" - function redirects to login page with flash warning rather than dying

plasma storage labels supply trial number in place of patient name; fixed error generated when supplying empty #labels option; provided '0' for number of labels to allow valid input for skipping label printing for individual requests

moved storage vial deletion validation to DFV method and added 'reason for deletion' form field; added centre id to mail_reports.pl cron log entry; ppm_and_results.pl uses IPC::System::Simple to capture more explicit tar error (was returning 'cannot stat file' msg without script name & location info); added inadequate unfixed specimen to weekly notifications

modified previous change to enable user with secure address to email - given lowest priority over contacts.lib entry and generic email address (as used by UCLH)
