unbreak django.forms.util(s) import for django < 1.7

Django 1.6 and before will not work with the new import naming, and full removal of old path was not removed until 1.9.

This conditionally imports the new name based on django version >= 1.9.

Tested locally in Django 1.6, and 1.7, and faked out the system by manually setting the version to 1.9

I think is better to import django.forms.utils from django 1.7 included to avoid a deprecation warning as I do in #34. Sorry for the first breaks of django 1.6 …
