As pointed out by Robert Pollak, there's a typo in the German
translation of the compression preset option (-0 ... -9) help text.
"The compressor" translates to "der Komprimierer", and the genitive
form is "des Komprimierers". The old word makes no sense at all.
Although the old address is still working, the new one should
be preferred. So this commit changes all three places in de.po
accordingly.
