Launch test for Baker 4.0 (shelf)

Baker 4.0 is a big step forward, adding support for shelf (support for multiple publications) and Newsstand (support for Newsstand, background downloads and in the future other Newsstand features). To ensure that the 4.0 release goes well, we'd like to have publishers that test it with us and publish on the App Store, in order to have proof that it gets approved.

What are the requirements to participate in the launch

1. The magazine must be free, at least at the beginning (we don't support In-App Purchase yet)
2. The Hpub of the magazine is ready (or almost ready)
3. A server to host the magazine and the shelf JSON
4. We don't have a release date, but we are trying to release 4.0 before Xmas, so it should be ready ideally by then, but let's chat if you have a different timescale.

Why Baker needs you

Because we need to make sure that Apple approves the upcoming version 4.0 before we publish it for everyone on the web.

There are still some details that need to be sorted out, but right now the master version is ready for publication: https://github.com/Simbul/baker/issues?milestone=8&state=open

Part 2, when it's ready for release
