added new counters for vep input rows and raw src_file rows; patched lab number regex to allow optional letter prefix; fixed test scripts to report vep input row count instead of 'accepted' rows
bugfix to _prediction_and_score() - needed to skip undef vars; colour-coded results if deleterious or damaging; truncated long (>30 char) variation results; re-ordered results cols for clarity
replaced / readline with IO::All methods pipe and getline; always returned defined content for sift & polyphen in _prediction_and_score() to avoid empty cells in results.tt; bugfix ngs.css
