Brian Clozel af3d62e9b5 Fix content warning issues over https
When served with HTTP/2 and TLS, project pages show several mixed
content errors:

* the imported Google fonts
* the AJAX call to spring.io to get the current project information
* the newsletter iframe

This commit changes URLs to use https or protocol-relative URLs when
possible. This also deletes the now defunct newsletter integration.
