add sample ID validation for Genomics; remove genomics.xsd symlink from repository tracking

dump_and_anonymise script retains patient year of birth (unless rand date would be in future); shell script needs to pass src db name to anonymise.pl for skipping Genomics db unit_number anonymisation; output every 1000 patients rather than 100

fix anonymise_db.pl failure to update nhs_number if value already exists in patients table and not yet replaced - didn't consider existing values when generating replacement nhs_numbers; adjusted vertical spacing of HaemOnc SLF for test server

spacer row required for HaemOnc SLF 2nd sheet

fix and simplify error return for Genomics slf type regex failure - not triggered by lack of \$slf_type_param but \$slf_type; provide short method name for CA::get_current_runmode()

split Genomics HaemOnc SLF into 2 pdf's to prevent position alignment slippage over multiple requests; tidy up contacts.lib

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

nee genomics_data.pl script

Genomics SLF selection form displays number of elegible requests; adjustment to HaemOnc query

replaced multiple td spacers with 'height' style declaration for Genomics HaemOnc SFL's, but cannot prevent vertical migration of 2nd page on multiple request selection

new Genomics HaemOnc SLF

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

replaced all consent form & info sheet version options with new format; created new schema to test genomics_cancer_v3.sql

separated validation profiles for new user created by a) copy/paste application message and b) user manager - username param now handled differently; 6 new tests for duplicate user first & last names

separated parsing of new user form params from creation of unique username; removed username from param validation as it's now generated and validated inside the new user function; validation fails on duplicate full name; new username only generated after successful param validation; appends unique numbers on auto-generated username until it is unique; TODO: editing existing user requires adjustment to validation function
