[NEEDS REBASE] fix bug 1068422 - remove Mozilla servers from example configs

@twobraids any idea? in my configman 1.2.7 I ran: `PYTHONPATH=. python demo/advanced_demo3.py --admin.print_conf=ini > output.log` and it did not put any trailing spaces after the doc strings. 

@rhelmer can you check which configman version you have installed when you ran this? It could be a bug in crontabber_app.py and not configman.
