Small German correction

* note_780_5 is "absorbed"
* German value translates to "absorbed into", so the other way round
* proper translation is "Darin aufgegangen" ("Absorbiert" would sound very chemical)
* see for MARC: http://www.loc.gov/marc/bibliographic/bd780.html
* German translation by Deutsche Nationalbibliothek is identical: http://d-nb.info/996983511/34
