[O] https://orgmode.org/ loads google font css through http

[Xu Chunyang]

Hi,

The source of https://orgmode.org/ contains the following

#+begin_src html
<link 
href="http://fonts.googleapis.com/css?family=Droid+Serif:400,400italic|Droid+Sans&subset=latin"
 rel="stylesheet" type="text/css" />
#+end_src

My web browser (Chrome) refuses to load it and shows a warning in the
address bar.
