[PATCH] git-gui: Update German translation.

Attached to avoid whitespace problems.

By the way, the newly added menu entry "Remote"->"Remove Remote" is highly 
user-unfriendly, as it isn't obvious here what the menu item will do and the 
cost of erroneously selecting this is rather high. Obviously this is the 
counterpart to "Remote"->"Add...", which, as the menu promises, will give me 
the opportunity to confirm what I'm going to do next. In contrast to 
this, "Remote"->"Remove Remote" doesn't ask for any confirmation, but will 
directly remove the link to the remote from my working copy. As a 
non-git-guru, restoring this link to the remote is a non-trivial task. In the 
sense of GUI symmetry and meeting user expectations, "Remove" as a 
counterpart to "Add" should be a menu item like "Remove..." which also waits 
for confirmation before removing the remote. Or did I miss something?

Regards,

Christian
