Changed argument "requires_modules" to "require_module"
for SeqFeature.t and transfac_pro.t, since its only 1
Added 'Data::Stag' requirement to many tests files
that depend on it, so they can be skipped if its missing
BioFetch.t & SwissProt.t: Fixed some number of skipped tests
and cleaned format and indentation
RemoteBlast.t: Fixed several number of skipped tests,
increased significantly server waiting cycle (sleep + retries)
because server was taking much longer than current setting
to return results, and cleaned format and indentation
