Add support for multidb with Django (Closes #171).

The ``factory.django.DjangoModelFactory`` now takes an extra option:

```
class MyFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = models.MyModel
        database = 'replica'
```

This will create all instances of ``models.Model`` in the ``'replica'``
database.
