Twitter has moved the end points for its API to 1.1 from 1

I'm getting 410 responses because the library is making requests to this end point:

```
api.twitter.com/1/statuses/home_timeline.json
```

when it needs to be 

```
api.twitter.com/1.1/statuses/home_timeline.json
```

now.

I'm not sure if you're still taking pull requests for this project? If so I can update the URL scheme pretty easily and send it to you?

Cheers, Jason.
