Python 3 incompatbilities in models.py

model.py uses basestring and unicode, which are gone in Python 3.

Also, there are a few issues stemming form the unicode-ness of strings in Python 3:

• model.TextField.db_value() converts to encoded strings, which would be bytes in Python 3. model.Query.get_primary_hash_key uses db_value to convert the primary key value into the Redis key suffix. So we end up with keys like user.id.b'joedoe'.
• model.Model.load() iterates over the field names, which are (unicode) strings and looks them up in raw_data, which is a dict with bytes keys, since redis.hgetall() returns all hash field names as bytes objects. Consequently all field values of the Model instance will be None.

@SpotlightKid, usually I try to be very nice as a maintainer, but don’t bitch about my library in one comment then tell me how to design it in another.

Walrus tests are currently passing with Python 3.6, so I think this can be closed out.
