Title: Allow the value of inline associations to be null

Allows for inline `belongsTo` associations to be null.

Before

```coffee
class Product extends Batman.Model
@belongsTo 'foo'
```
```
'product': {
'id': 1
'foo': null
}
```

Would raise an exception if the association was null when decoding.
