Bring CircleCI back to life

[JJ]

Problem

CircleCI is repeatedly failing. This is a complementary test to the main ones, building the documentation using Documentable. It fails with a timeout, after documentable start -a produces no output for 10 minutes.

Suggestions

Documentable has undergone lots of changes lately, but it should definitely produce some output. Check it out and rebuild the used stack if needed.

Created an issue in antoniogamiz/docker-documentable#1 which is the repo for the container used in CircleCI

Well, letting it show output made it work; the problem is still it's taking a long time, 18 minutes, and IARC there's a limited amount of "credits" in the CircleCI free tier, so we might still get errors by the end of the month. I'll try and see if we can speed it up, or use caches or something.
