Submission proposal: Newebe

Hi @al3x,

  Here is my submission for Newebe (more infos here: #228).
It sets up three daemons:

* Newebe: a Python program that runs the Newebe instance.
* CouchDB: The database used by Newebe.
* Supervisor: a process manager in Python that manages the Newebe daemon.

It adds a configuration to Apache2: 

* a reverse proxy between newebe.{{soevereign_domain}}:443 and localhost:8282.

I hope everything is ok. Tell me if I must change something.

Regards,

Frank
