user/users name clashes; patch in README seems to need update

[ghost]

when I applied patch indicated in README, name clashes were reported for both user and users; I changed the related_names of both, which stopped the error, but I have no idea whether it introduces new problems:

in /src/eggs/django_friends../friends/models.py, about line 43:
    user = models.ForeignKey(User, related_name="friend_contact")
    ...
    ...
    users = models.ManyToManyField(User, related_name="friend_contacts")
