unescaped :accession and url values (bgee makes it necessary)
added  rdf:type Evidence to peptide mapping evidence
validated by Pascale., see mail 27.10.2014
gave a :EXP type to the evidence too
when :start object value is 0 (unknown), then the predicate is ignored, idem for predicate :end
fixed bug causing assignmentMethod and qualifierType to be mixed
