Title: Add commentOnDiff method

Fixes #2

Enables commenting on a line of a diff with:
```javascript
pull.commentOnDiff({
body: 'comments all up in ya code',
commit_id: 'fd9e30492ae661058afe532ed6cfc0cb6d1d644f',
path: 'relative/path/to/my/file.js',
position: 4
})
```

Or if you know a comment id, you can reply with:
```javascript
pull.commentOnDiff({
body: 'ya I agree',
in_reply_to: 123
})
```

Cheers!
