Update the translations after the recent GUI changes. (TODO: French translations.)

As the title says. Ico and Guillem updated the English translations alright, but didn't add the new entries to the other two translations we have. There were also two earlier entries missing in the German translations. I added all of those now, the French translations still need actual translation, though. :)

@Joseph, could you please provide the French translations for the following items?

Note that I already did "saveas", that was easy enough. ;-) If you need help with any of the other options, I'm happy to explain what they are about.
