Add dependency_links entry for django-formtools...

... pointing to a fork which allows installation on Django 1.6+ This is to support environments running Django 1.6.x that also are strict about dependency versions and conflict resolution. Well commented, this can all be removed when we drop Django 1.6 support.

+# NOTE: divio/django-formtools is IDENTICAL to django/django-formtools except
+# that its Django requirement has been relaxed to >=Django>=1.6. This is because
+# this version of django CMS supports Django 1.6+. Internally, CMS will use
+# django.contrib.formtools when available, then look for the external version if
+# required. Unfortunately, SetupTools doesn't allow use to load the external
+# library when using Django 1.7+ only.
+#
+# Further note that dependency links do not work by default. Current versions of
+# Pip support it with the flag `--process-dependency-links`
+#
+# Remove these machinations in CMS v3.3 when Django 1.6 support is dropped.
