enabled SSL for the webserver

[formtapez]

This is a quick demo how to enable SSL on the webserver. Seems to work pretty well.
I created cert & key using
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ssl.key -out ssl.crt
but you also can use LetsEncrypt or other certificates.

• Needs to be configurable whether to use HTTP or HTTPS, requiring HTTPS with certs will break CI testing
• Should support ACME services such as Let's Encrypt or any of the other alternatives for easy zero config setup i.e. auto managed certs and keys. Maybe config option to use manual cert and key?
