Issues during translation

I was working a lot on the german translation this weekend and found a couple of issues while translating regarding gemeral issues and internationization

• solve issue with French region names: e. g. Departements seem to be hard-coded into the strings
• sometime email-adresses in strings
• trimesters and semesters are not suiting to school and university systems around the world

I don't know how the core developer team want to handle especially the things special to france that cannot be applied to the rest of the world.

Still I hope this helps a little bit
