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
added errors & alerts display to results output; checks all exon names in src data are in vep input data; updated test scripts with results output format
