simplify shipfile

[notslang]

Right now the shipfile can hold multiple deployers, but most projects only need one deployer, so the data-structure that's needed for multiple ones is quite a bit of overhead.

So, I think I'll make it so a shipfile only has one deployer, and if you want to deploy to a different place, you just specify a different shipfile. This also neatly solves the issue of having separate staging vs production environments (you could have a shipfile named ship.production.json and another named ship.staging.json).

And the format for a shipfile would be:

{
  "sourceDir": "./public",
  "deployer": "gh-pages",
  "sourceDir": "public",
  "projectRoot": "./"
}

I'm on board with this. Roots 3 handles config files and environments this same way
