Title: Allow inheritance on classes based on RedisModel

The only bug was the `_field` and `_hashable_fields` attributes which didn't include fields
from parent classes

This patch allow this :

```python
from limpyd import model as model

class BaseRedisModel(model.RedisModel):
updated_date = model.StringField()

class MyFirstModel(BaseRedisModel):
some_field = model.StringField()
```
