update 014_data.t to match previous change in VEP error msg * document Log::Report issue with D1 & D2 version

moved NGS::Test function to NGS::Test::Common & moved test-lib.pl functions to NGS::Test, removed all calls to test-lib.pl from tests

major rewrite of test scripts - adapted for D2 version .154 - replaced D2::Test with Plack::Test; new NGS::Test Import::Base class

major version change: refactored _run_vep() to select consequence, variation, sift & polyphen values from specified gene/feature combination (multiple entries for same exon_id from vep, with varying sift, polyphen, consequence & variation vals taken into hashref meant last one wins); added cds and protein annotation vals; vep data row skipped & warning issued if ENSG0000* gene id not present in transcripts db

added functions to retrieve and display vep api_version and app version

minor adjustments

added myseq.zip to repo; minor presentation tweaks

updated test scripts to work with previous app upgrade (eg tests merged db)

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

patched VEP::_get_hmds_refs to return error if col header doesn't look like lab number; 015_data.t to test

fixed refseq selection function - required separate cache dir & use of --dir option
