Thanks Joachim!

I've added a script which can compare languages against the English in order to identify missing strings, translated strings which are no longer used by auspice etc. This identifies:

$ npm run diff-lang -- de
...
DE: comparing translation.json against the English translation
        Following keys are present but are simply a copy of the English version & need to be translated:
                "reset zoom"
                "Journal"

If you just let me know the translations of these two (perhaps "Journal" is the same in german?) I can add them to auspice, or feel free to submit a PR. But missing two strings for a language is relatively minor!

Oops, I missed those:

• reset zoom -> Zoom zurücksetzen
• Journal -> Zeitschrift
