Use HTTPS for links without protocol

[popod]

It will be a great idea to use HTTPS by default for links without protocol. Or at least add an option to enable this feature.

Actual

www.test.com -> http://www.test.com
http://www.test.com -> http://www.test.com

With HTTPS by default

www.test.com -> https://www.test.com # we use HTTPS by default
http://www.test.com -> http://www.test.com
