Glad to see that the project is alive again.
Synced the pull request to upstream as of March 1, 2018. The Travis setup seems to be broken, so tests did not run.
Maybe you can have a look?

After several years of inactivity, authomatic is now under community management, and we have just released a new stable version (1.0.0).

We are now reviewing all issues and PRs and hoping to begin work to solve as many of these as possible.

We are keen to find out which issues still apply, and which PRs are still required/are likely to merge cleanly into the current code. We are aiming to review them all, but any help with prioritisation would be very useful!

If you are still interested in having this issue/PR resolved, or are able to help us work on it, please reply to this message. That way we know which issues are most important to the community.

(Note: the travis build will always fail for branches outside the authomatic repo - however it should still run some basic tests like code linting which are of use).

Glad to see the project alive again.
Still interested in making the pull request work.

Great! We're in the process of overhauling the test suite so the results are still useful for PRs (#205 ) - once that's done we'll merge master back into these PRs and see where they stand.
