By default, open response assessment files are sent to S3. Here, we
store uploaded files with the "filesystem" backend instead. To do so, we
must install a forked version of ora2 that fixes a couple issues.
Note that the "django" backend is not very usable, as file extensions
are lost on upload.

Theme assets generation relies on a cache stored in memcache. We were
observing incorrect urls generated for theme/xblock assets whenever
assets had been generated for another platform. For instance, when
viewing an XBlock in the LMS right after running "paver update_assets"
in the cms.
To solve this problem, we cache staticfiles assets in entries with
different prefix.

Template files are now directly loaded in the configurator container, so
that it is possible to run the configurator container directly, outside
of this project.
