Subject: [PATCH] MusicXML: Convert words, assigned to staves => assign to
 notes in Lilypond

In MusicXML, words are represented in direction elements, in Lilypond, they
are assigned to notes....
Also try to convert as many font attributes as possible (several are still
missing, currently only text-size and text-wight are supported)
