Fix for SwissProt parser issue #369 from Leszek Pryszcz

The UniProt 2014-10-01 release adds new evidence codes to the
plain text SwissProt format, which were breaking the parser

ignoring the new fields.
PEP8 fixes
Ignore evidence code for SwissProt keywords

Doing this to match the UniProt XML parser.
