Documentation Tab empty when using HTTPS

[rbi]

When I go to the Documentation Tab on the HTTPS version of the
katharis.io Website I get an empty page. I've tried it in Firefox and Chrome (see Screenshot).

I can open the page http://katharsis-jsonapi.readthedocs.io/en/latest/ manually and the documentation tab works when I visit the HTTP version of katharsis.io so my browser may just want to guard me from an insecure website.

I don't think my PR fixes all the issues with that. I couldn't find the spots left with http requests yet.

We fixed fonts.googleapis.com with my PR. But the rest needs to be updated as well

Roger that. I'll look at it today.
