Update package.json

There is a problem with this module, see below. I fixed it by using version `2.0.0` of the `connect` module.

```
TypeError: Object function createServer() {
  function app(req, res, next){ app.handle(req, res, next); }
  merge(app, proto);
  merge(app, EventEmitter.prototype);
  app.route = '/';
  app.stack = [];
  return app;
} has no method 'query'
