Cannot import UNUSABLE_PASSWORD with Django 1.6.2

[ghost]

Hi, after upgrading to Django 1.6.2, registration-me produced an error:

ImportError at /accounts/login

cannot import UNUSABLE_PASSWORD

A solution was to change registration/forms.py and replace

from django.contrib.auth.hashers import UNUSABLE_PASSWORD

with
from django.contrib.auth.hashers import UNUSABLE_PASSWORD_PREFIX

And change in PasswordResetForm:

if self.users_cache.filter(password=UNUSABLE_PASSWORD).count():

to

if self.users_cache.filter(password__startswith=UNUSABLE_PASSWORD_PREFIX).count():

I wonder if this is a good solution?

Looks like it could be acceptable. Thank you for your suggestion.
