[tex-hyphen] German patterns in TL2010

  We'll need at least one English(-sounding) name for the language name,
but I don't see why we couldn't use aliases in language.dat like for
other languages (French has "francais", Spanish has "espanol",
Portuguese has "portugues", etc. -- and those one aren't even correctly
spelled since we had to strip the accents).
