Subject: added support for custom slug field and kwargs

without subclassing HyperlinkedRelatedField and overwriting
slug_url_kwarg and slug_field there is no possibility to use other
fields / arguments. now you can do something like this:

url(r'^users/(?P<username>\w[\w-]*)$', UserInstance.as_view(),
name='user-detail')

class ProjectSerializer(serializers.HyperlinkedModelSerializer):
    created_by =
serializers.HyperlinkedRelatedField(view_name='user-detail',
slug_url_kwargs='username', slug_field='username')
