try removing data_files -- they're getting installed incorrectly!

$ pip install django-olwidget==0.61.0

on a docker container (i.e. not within a virtualenv) resulted in the following distribution of files:

  /usr/local/lib/python2.7/site-packages/olwidget/__init__.py
  /usr/local/lib/python2.7/site-packages/olwidget/admin.py
  /usr/local/lib/python2.7/site-packages/olwidget/fields.py
  /usr/local/lib/python2.7/site-packages/olwidget/forms.py
  /usr/local/lib/python2.7/site-packages/olwidget/models.py

  /usr/local/olwidget/templates/olwidget/admin_olwidget.html
  /usr/local/olwidget/templates/olwidget/editable_layer.html
  /usr/local/olwidget/templates/olwidget/info_layer.html
  /usr/local/olwidget/templates/olwidget/multi_layer_map.html
  /usr/local/olwidget/templates/olwidget/test_map_template.html

Thus Django was unable to find the templates or static files.

The data_files attribute in setup.py does not appear to be designed for the likes of django templates/static files. Simply removing it has resolved the problem for me. However I'm not an expert on setup.py so I may be missing some nuance as to why data_files was being used...
