[PATCH] translated German comments and removed redundant ones

[Florian Allmann-Rahn]

Hi,

After some time I have another load of translated German comments ready.
The patch is attached and after applying it the directories 
connectivity, cppuhelper and cui should be completely cleared of German 
comments. The changes are as always under LGPL/MPL. I hope the patch is 
fine and will work :)

Best regards
Florian
