Use Zine's webserver hosting for examples

The Zine project has a nice development server which would be great for both easy hosting of examples (so users don't build and then go "how do I see it?"), and also for iterating during development.
I just chatted with @kristoff-it and the plan is they're going to pull it out into a separate project from the Zine repo.  Once that's done, integrate it with the examples here.
