Resolve #159 -- Add custom JSONEncoder support via setting

[N1K1TAS95]

Added support to set a custom JSON encoder via Django settings.py

Excellent! This should do the trick. I left you a suggestion for your documentation. I'd like to keep a little shorter, while adding more backlinks to the Python docs. They actually have a pretty good example on how to extend encoders. We use inter-sphinx to create those links, if classes are marked accordingly in the docs.

Oh an @N1K1TAS95 you'll need to move the docstring under the attribute, to make it work. I'd recommend running python setup.py build_sphinx to check the docs locally.

@codingjoe I've moved attribute docs under the attribute itself.
python setup.py build_sphinx compiles and docs are updated with new attribute. There is also a link to Python docs JSONEncoder.
