Rerun for new ecliptic transformations

[astrojuanlu]

These two PRs were merged to Astropy since the results were last generated:

• Fix ecliptic transformations astropy#6508 (I explicitly show a screenshot with the ecliptic improvements there)
• Add more ecliptic frames astropy#8394

Is an empty commit on master all we need to regenerate the results and the tables?

I've just:

• Triggered a Travis build
• Set up a monthly cron job
• Added you as a maintainer of this repo so that you can easily restart/trigger builds if needed and help maintain this repo 😄

So one issue to resolve is that I think this repo is still on Python 2 and we should update to Python 3 (#43) otherwise we won't pick up Astropy 3.x...

[astrojuanlu]

Tackling this soon, now that #63 has been merged.

Finally, the "new" ecliptic comparisons are online 🎉 http://www.astropy.org/coordinates-benchmark/summary.html

...Although they look more like the "wrong" results I captured in astropy/astropy#6508 (comment), possibly because of a True/Mean mistake.
