Title: add a way to whitelist attributes to serialize.

I needed to pick which nested attributes are being send to the server.
Just add an array of key to the relation.

```coffeescript
relations: [
type: 'many'
key: 'thumbnails'
relatedModel: -> Entities.Thumbnail
serialize_keys: ['id', 'x', 'y', 'height', 'width']
]
```
