3.1.x Deployment

Steps:

1. Backup Compose Database (click backup now)

2. ensure you've tagged a release, enter it here, and check it out in git

3. Go into compose, delete the eventCategories collection.

4. Delete the addons collection

5. Ensure that prod & qa settings files contain the same keys (i.e. make sure we didn't add any settings)

6. use the prod settings, deploy to galaxy: DEPLOY_HOSTNAME=galaxy.meteor.com meteor deploy ucbapp.meteorapp.com --settings private/prod_settings.json

7. test the rules fixes (donate clothes, duplicate submissions, and a smattering of selfie rules + a pre-listed event or two)

8. If issues are discovered, try immediate fix or re-deploy prior tagged release (3.1). Make sure to delete eventCategories again.
