refactored Roles::PDF so that all reports are generated by same method inline_html_to_pdf_no_webkit() so reports should be identical whether by print run, individual print or print_run.pl cron, and only have one sub to define pdf settings for all functions; print_run.pl takes getopt -t for test; moved family_id validation prefix definition to settings.cfg so test & live can have different values; new entry for pcr_and_sequencing_worksheet.tt

fix error in date calculation - datetime col needs DATE() for single day; moved dump_query() to LL::DBIxSimple and Local::DB

adapted print_run.pl to save test file to /tmp and to use today -1 day as end_date->ymd - will be correct if run manually at any time during day

modified print_run.pl to accept cc reports - required new RecordHandler method to return private sub; patched dump_query() to auto-increment index counter at end of sub instead of inline during block - didn't work properly

new cron print_run.pl; amended default.tt to load date of print-run pdf and avoid clash with 'date' tt param
