Planet Python, https and rendering of the site. #230

On the communicating.html page of devguide, there is a link to the planet python site, but this one is only in http. There is a support of https, the certificate seems to be good

$ echo | openssl s_client -servername www.planetpython.org -connect www.planetpython.org:443 2>/dev/null | openssl x509 -noout -dates

notBefore=Apr 27 16:10:00 2017 GMT
notAfter=Jul 26 16:10:00 2017 GMT

but Google Chromium and Firefox tell me that the connection is not fully compliant with https, and in fact, some images or css files are not reachable.

404 error

https://www.planetpython.org/js/iotbs2-key-directors-load.js
https://www.planetpython.org/js/iotbs2-directors.js
https://www.planetpython.org/js/iotbs2-core.js
https://www.planetpython.org/styles/defaultfonts.css

and because these files are missing, the rendering of the website is just ugly.

thank you
