Incompatible with django-filter 2.x

Discovered that using djangorestframework-filters==0.10.2 with Python 2.7 led to:

File "/usr/local/lib/python2.7/site-packages/django_filters/__init__.py", line 4, in <module>
    from .filterset import FilterSet
File "/usr/local/lib/python2.7/site-packages/django_filters/filterset.py", line 184
    def __init__(self, data=None, queryset=None, *, request=None, prefix=None):

Turns out that

From Version 2.0 Django Filter is Python 3 only. If you need to support Python 2.7 use the version 1.1 release.

Hi @kwigley. Notice that the error is occurring in django-filter. Most likely, you've unintentionally upgraded to django-filter v2.0, which was just released and is Python 3 only.
