Upgrade django filter

[rpkilby]

Hi all, this should (hopefully) resolve all of the django-filter issues, migrating you to the upcoming 1.0 release.

should fix #2490, fix #2495, fix #2498, supersede/resolve #2499

Agreed, RTD maintainers can skip #2499 in this case - or in case they want to wait for the final django-filter 1.0 release, they could leave this PR until the release day.

@rpkilby how ready do you estimate the current django-filter develop branch to be? Or when would you guess it's shipping?

[rpkilby]

1.0 is pretty much ready for release. Unless any new bugs are found, the only thing left to do is release it to pypi.

[benjaoming]

Cool, in that case I think we should wait for 1.0 on PyPi, and then add django-filters>=1.0,<1.1 to the requirements file to get rid of the old unpinned git dependency.

I'll hold off on this, and ship it once the 1.0 release is on PyPI.

Hi @ericholscher - django-filter 1.0.0 has officially been released. I've updated the pip reqs to lock it at 1.0

Thanks for the update!
