Introducing setup_for_film functionality

It is now possible, only for user with admin capability, to setup a
project as ‘film’. This action can be performed via CLI using
./manage.py cloud setup_for_film <project_url> or via the web
interface in the Cloud settings area.
Setting up a project for film creates a number of extension props
under the ‘cloud’ key. Such properties are listed in the
cloud_extension_props variable in setup.py.

At this moment the functionality exists for a very specific purpose:
improving the presentation of public Film projects in the Blender
Cloud. It can be further extended to improve the presentation of
Training and Libraries later on.
