German Translation added

Hi there,

I just translated the gitbook from english to german and added a second folder. I have a couple of questions/suggestions though.

Suggestions:
1) Include this whitepaper https://github.com/maidsafe/Whitepapers/blob/master/Project-Safe.md 
2) Include the various FAQs that are on the maidsafe.net, maidsafe.org and google mailing list.
3) Add the build instructions, create a structure for the different plattforms (Linux, Mac, Windows) that can be used throughout the document.
4) Merge this one with the SystemDocs?

I think it would be better to create a central place for the documentation. If we're using a gitbook anyway then let's combine it in one big book where everything is ordered by chapters. 

Questions:
1) Are there additional information for the local_network_controller or the buliding process in general? I don't think the instruction are very clear following the succesfull build. Right now I have no idea where the local_network_controller is supposed to be. Maybe you can point me in the right direction?
 
EDIT: Forgot to mention this. If you're ok with the suggestions, I can merge those documents and also add the translation, just let me know. 

If you have any questions, or if there is anything else I can do, just let me know. I 'm happy to help.

Regards
