typo

Hey, ty for the example, helped a lot!

Small annoyance, might bug other people: My client sided receive handler just did not want to work, while yours did - and it took me half an hour to figure out that the server emitter (in sync with your app.js) had a typo:

> ```
>             self.emit('recive', redis.lrange(key, -1, -1))
> ```

receive ;-)
