minor tweak to xml_validate.pl for clarity

adapt xml_validate.pl to run as cron to email validation failues

* add new Genomics v3.2 fields to validation function * expand validation error description on some Genomics results * add BHODS HL7 script

update crontab.txt with current cron tasks; add new entry to genomics_notifications.pl; add getopts to xml_validate.pl

created error code map for genomics participant ID error (previously got undefined variable warning); new function to expand 30-character result limit for Genomics data; Genomics v3.2 deployment script updates

moved error reformatting to GenomicsValidation for sharing between genomics_xml.pl & xml_validate.pl; replaced message formatting mess with Template

bugfixes to genomics validation scripts; remove numbers from new section names format; rearranged schema update - more efficient using sql variables

moved xml and param validation out of xml_validation.pl and genomics_xml.pl into new LL::GenomicsValidation class

tightened family_id validation to match existing participant_id + 1st 3 digits of participant_id base range

participant_id comparison uses Local::Utils::matches() to handle numerical or non-numerical values

modified previous validation - wasn't compatible with test/UAT participant ID blocks

added participant_id validation

removed invalid xml participant id entry 'UNKNOWN' if request unscreened

bugfixes: don't skip request if validation fails for genomics.t; can't use content_contains on string with line-break

bugfixes a) auto-vivification in genomics_xml.pl, b) auto-vivification didn't cause validation failure in xml_validate.pl as params validated after xml created - changed to same order as in genomics_xml.pl; applied same fix as genomics_xml.pl to return value from validate_params() in xml_validate.pl
