Don't automatically bind to `localhost`

[indexzero]

We should find a way to work around this in haibu-carapace, but right now a simple static site is broken on http-server@0.4.0:

e.g.: http://github.com/indexzero/presentations/tree/master/couchconf-nyc-2011

{
  "name": "couchconf-nyc-2011",
  "version": "0.0.0-3",
  "author": "some-guy",
  "subdomain": "couchconf-nyc-2011",
  "analyze": "false",
  "dependencies": {
    "http-server": "0.4.x"
  },
  "scripts": {
    "start": "node_modules/.bin/http-server"
  }
}

Fixed somewhere.
