New pypi release to fix dependency issue with Django 1.11.x

[livenson]

We are using Django 1.11.4, which should totally work, but the installation is failing due to a conflict:

error: Django 1.11.4 is installed but Django<=1.11,>=1.8 is required by set(['django-defender'])

Seems to be ok with master -- but we'd need something from pypi. Thanks!

0.5.2 is now on pypi : https://pypi.python.org/pypi/django-defender/0.5.2

Thanks! It would be great to get another release once #115 is merged. We are packaging defender into RPMs and these extra dependencies are not making life easier at all.

@livenson yes, I was hoping to have everything in this release, but didn't want to keep everyone waiting, hopefully we can get the other PR's merged, and once we do, I'll do another release.

@kencochrane , any chance of doing a 0.5.3 release with dropped mock dependency?

0.5.3 is on PyPi https://pypi.python.org/pypi/django-defender/0.5.3
