Upgrading django 1.10

[XaviP]

Removing RemovedInDjango110Warning still in dj1.9:

---

About RemovedInDjango110Warning: Support for string view arguments to url() is deprecated and will be removed in Django 1.10:

• Include the import needed in each urls.py file and remove simple quotations in view argument:

vim valuenetwork/valueaccounting/urls.py # add at the top: import valuenetwork.valueaccounting.views
sed -Ei "s/'(valuenetwork\.valueaccounting\.views\.[^']*)'/\1/g" valuenetwork/valueaccounting/urls.py

You'll need a manual checking because of other possible imports/removes needed, but the main work is done.

• This must be done in any urls.py file shown in:

cd [installation dir]
find . -name urls.py

• There's one RemovedInDjango110Warning of this kind that points to django-notification package. We need to change django-notification to pinax-notifications. See these changes:
  FreedomCoop/valuenetwork@7efb5cc
  FreedomCoop/valuenetwork@0ee56b0
  FreedomCoop/valuenetwork@1cd8f5e
  FreedomCoop/valuenetwork@71972ff

About: RemovedInDjango110Warning: django.conf.urls.patterns() is deprecated and will be removed in Django 1.10. Update your urlpatterns to be a list of django.conf.urls.url() instances instead.:

• urls.py files cannot use patterns() anymore, it must be in the form:

urlpatterns = [
    url(...),
    url(...),
]

• Remove patterns from all from django.conf.urls import patterns, url
