Check if de translations match Ardublock labels

[rin]

Check if the German translations match those from Ardublock.

1. Install Ardublock and document their labels OR export them from Ardublock code.
2. Check if there are differences. – If there are, it might be worth checking which translation is "better" (=more suited for kids, easier to understand). I'm guessing we don't have that much documentation/material that we'd need to change if we changed these.
