Boilerplate appveyor.yml file for running Node.js tests on AppVeyor

Because it's so much harder than it should be...

• Go to the AppVeyor website and add the repo you want to test.

• Fetch the appveyor.yml file directly:

   $ curl -fsSLO https://github.com/sindresorhus/appveyor-node/raw/master/appveyor.yml
  

  Or download it manually. (Right-click and choose "Save link as...")

• Add the badge to your readme. You can get it here:

   https://ci.appveyor.com/project/{user}/{repo}/settings/badges
  

  Replace {user} and {repo} with your GitHub username and repo.

• Commit and push.
