skip trial reportts from print run; merge Model::PrintRun _print_run_excluded() and get_print_run_request_ids() to get single query, but RDBO cannot handle complexity so need to replace with SQL::Abstract::More method as used by print_run.pl
tied print_run.pl script to 'print_run_skip_trials' config setting so that both manual and automatic report generation produce the same output with a single config change
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
