Procfile -n flag

Hello,

I noticed that I needed the following in my Procfile:
`web: bin/hubot -a slack -n Hubot`

Without the -n Hubot flag I was getting the following in my Heroku logs:
`Process exited with status
 0`


Heroku log snippet:
```
[Sun Apr 06 2014 21:51:20 GMT+0000 (UTC)] INFO Data for brain retrieved from Redis
[Sun Apr 06 2014 21:51:20 GMT+0000 (UTC)] INFO Successfully authenticated to Redis
State changed from starting to up
Process exited with status 0
```

Let me know if you need any more information.

Thanks
