[BUG] Django Basic as middleware

[Bernardo Torres]

Using Django basic authentication as middleware.

settings.py:

MIDDLEWARE_CLASSES = (

...

    'django_basic.middleware.HttpBasicMiddleware'

)

Returns errors as some imports are missing.

The process_response should return the response itself, but it returns None. So it's better to erase it.

Attached goes fix.

Best regards.
