Be able to use the latest version in production

The current version has quirks to it that prevents us from using it in production. The version we use in production is not running as a Docker container.

The specifics of why the latest version is not usable, I'm not sure of. @KariRudjord will have to explain it.

I'm not sure about when we'll have time to work more on this, and whether or not it makes sense to wait for a new version of PIP (based on the work done with/by Dedicon++), but not being able to run the system in Docker is making things a bit more difficult when integrating with the rest of our systems, so I'm opening this as an issue.

Note: I've build a docker image for the current version we're using (which is not the latest version of the braille scripts): nlbdev/pipeline:2018-working-pip. So we might soon be able to use a more recent version of Pipeline 2 for everything other than the braille scripts.
