[open-data-manual] ODM German translation

[Daniel Dietrich]

Hi all 

Marian Steinbach (in CC) has started a german translation of the ODM. Hurray!

Its on guthub: https://github.com/marians/opendatamanual/

we are going to use this fork as the official German Translation and would like to publish this at de.opendatamanual.org

Also: My understanding is that the ODM is "work in progress" itself so we would also like to get write access to the original at github to be able to feed back improvements and amendments that we might want to do working through the chapters. 

What do people think?

Regards
Daniel
