pantheon.yml calls quicksilver-pushback but it is not installed.

Is this needed? If so, we need to add it. If not, we need to remove it from the pantheon.yml

  sync_code:
    after:
      - type: webphp
        description: Push changes back to GitHub if needed
        script: private/scripts/quicksilver/quicksilver-pushback/push-back.php

I don't think we need it honestly. I thought it was buggy but I also know it hasn't been used all the time.
