moved all db queries to NGS::DB; added download facility for processed data; new MySQL ngs db for download data

moved forking config to config files - dev server faster without forks, deployment optimum with fork = 2; moved hires timer to immediately either side of vep script loop; deleted vep input file from /tmp if exists due to generation using append mode (in case previous run aborted before unlink) event; output format tweaks

changed script/variant_effect_predictor.pl file to symlink to same file inside variant_effect_predictor dir for ease of updating vep version - now just download, extract & run new v_e_p.tar.gz

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
