Config sample preparation

The first commit is the manual copy of @carlaschroder 's initial work on the documentation. The second one is the result of my script. (I used the stable7 branch of owncloud/core for this.

I have wrote a little script that will check for changes every night and mail me if something happened. Once this works reliable I could ask @DeepDiver1975 to set it up at Jenkins to have the deployment of this in an automated way (the same way as the translations) This script can be found at: https://github.com/MorrisJobke/ownCloud-config-converter/blob/master/updateConfig.sh

@LukasReschke @wakeup Have a look at this.
