Updated/redid de.po.
I have *not* changed all the other .po files, I've done "make
update-po", that's all. Please kill me, should I have messed up the
tree somehow.
Kill me anyway, should I have goofed with CVS somehow. This thing
scares me no end, I keep looking stuff up in the documentation, and
it's with trembling fingers that I do my commits. Luckily I can't
break any code since I don't work on any code :)
