Newebe: improve playbook and don't fail on first installation

- Add test
- Fixed Newebe's playbook failing on first run on a fresh Debian 7 VM
- Restart supervisord on changes
- Security: Use /usr/sbin/nologin as login shell for newebe user
- Speed: Consolidate all 'apt' entries into one
- Strip trailing whitespaces
- Update to take advantage of apache2_module from Ansible 1.6
- Use file path=... state=absent instead of "rm" command to delete files
