Django 1.9 incompatibility

[fabian-marquardt]

Django 1.9 has been released recently. Using this version, django-mongodbforms fails to load with the following exception:

  File "/usr/lib/python3.5/site-packages/mongodbforms/documents.py", line 11, in <module>
    from django.forms.util import ErrorList
ImportError: No module named 'django.forms.util'

There is already a pull request to fix this issue. Please merge this code to the master branch.

I've forked this project and released django-mongoengine-forms on PyPI. I've stripped out a lot of the legacy stuff and it should be compatible with Django 1.9.

If you find any issues I'd be very happy to hear them.

nice @thomwiggers ! I was implementing the 1.9 compats but I'm gonna try to use your fork. We've developed a few useful features and fixes on our side, I might to a PR on your repo :)

sorry that looks awful; I'm not a git person obviously :(, but maybe an old git :)
