Plugging in files for tory-register docker image

Right.  I wouldn't say that's unreliable, though.  It's just not what you were expecting :wink:  The auth token assigned to a given repository that's been activated on Travis should stay stable unless it gets de-activated and re-activated by someone else.  Given that I don't think the Travis team is going to change the webhook payload any time soon, I'd say your vauth package will probably have to be modified to deal with a cascade of valid auth tokens or some such.
