Scripted auto-commit on change

@KartikTalwar @gdmalet  @colinbellCA @PavolC @krisolafson :
I have now set up auto updates with the service account on api1. I have it committing it to the autoupdate branch for now. Once we see it's stable with no hiccups we can move it over to push to master. For now I can manually accept the pull requests. Thoughts?
