Setup RSVP project config

RSVP is currently publishing AMD and browser rsvp packages.  I'm using the wildcard entry because RSVP has no channels at the present time.  This will publish on each push that has valid AWS credentials.  

I suspect this cannot be merged until after https://github.com/tildeio/rsvp.js/pull/263. 

Would love to talk this out with someone.

They are not only for test fixtures.  Thought, I have been debating with myself about where these things should live.  If they exist in the project, the project can change/update them at their pace but testing would have to also live in the project.  And that seems like a responsibility of this project.  I'm of two minds.   Perhaps, I could optionally allow a project config to be specified and then the including repos can decide as they will.
