Add translations and fixes to 1.9 master

Added translations, fixes to syntax errors and other minor fixes for
text strings.

Tested all changes. I hope not to break anyhting…

I was unsurem, but the menu bar on the Lite GUI dissapeared. Looking at
the commits on master, it seems that it wasn't me.
