jpn-(deu|eng|fra|rus): provide parsed part-of-speech information

[humenda]

For all mentioned dictionaries, part of speech information is annotated like this:

  <note type="pos">adjectival nouns or quasi-adjectives (keiyodoshi)</note>

It would be great if this could be converted to <pos/> elements and if possible, linked against an ontology. This way, the part of speech would be parseable by machines and could be localized for humans.
