add ssl-opts flag, describe all flags to readme

I use interlock with shipyard and i really miss ability to specify tls versions and ciphers to secure connection against poodle, heartbleed, beast attacks.
So i decided to add ssl-options directive to controller.
Unfortunately i can't check if it works because i can't understand how to compile app. Also there is a couple of hardcoded dependencies to github.com/ehazlett/interlock.
So can you describe, what should i do to fork and compile it properly?
