Minor mods to fix nested_inlines

nested.js ->  inlines.min.js + sugar

This suggests https://github.com/Soaa-/django-nested-inlines/issues/2

Because it has a minor bug that spawns the nested row with colspan=0
we append an minor js snippet that takes care of it.

Remove django.utils.six module from nested_inlines

This is a module that helps writing compatible code
for python 2 and 3. As long as we we support only python2
we do not need this (this does not exist in ubuntu django
packages)
