links not working reliably in Firefox

Using stylesheet link tags in the body of the HTML was not working
reliably in FF. Replacing with JavaScript fixes this.
added noscript if javascript is disabled
font loading broken on FF 23

The lastest version of Firefox has introduced a new security policy
for https connections that prohibits loading of html, scripts and
fonts over http.

This commit fixes the loading of the Comfortaa font from Google by
making sure to use HTTPS when the main page is loaded via HTTPS.
switch to using JSON detect via jquery

Injecting a style link in the page does not work with latest version
of Firefox due to new HTTPS security policy. This commit changes
the detection to use JSON via jQuery. I don't know if this will fix
the problem (can't test on dev system).
