tiny code cleanup
make German extend the BaseTagger class for less code duplication, now that the BaseTagger cares about loading additional data from "added.txt"
The part-of-speech tagger for most languages can now be extended by adding entries to the file org/languagetool/resource/XX/added.txt (XX being the language code). The format is "fullform baseform postags", three columns separated by tabs. This makes it easier for users (and developers) to extend the POS tagger, as they don't need to export, modify, and re-create the binary dictionary for every change.
