It now correctly references the current pot and version. Consequently, it
should be usable without generating a warning from the current
development iteration of gitinspector.
This commit updates the German translation. Changes in translation
include updating for changed messages in upstream and some rewording.
Also, this commit includes a different translation for "cyclomatic
complexity" because the previously used one (by inventor's name)
might be less clear than the current, literal translation, which seems
more intuitive, especially in a world where English is dominant in
software dev, so people are more likely to know only the English word.
Some translations have been changed to be more clear and to the point.
Some comments have been added to messages that have been causing issues.
