Update README.md to reflect HTTPS support

README.md

 # ip-project-server
-Server for Integrated Project, powered by Express.js and Redis, will eventually use HTTPS so passwords aren't sent unencrypted, need to get some certs. Also at the moment server responds to `ALL` requests, cause it's easier to do testing with `GET`, will also set up unit tests in good time.
+Server for Integrated Project, powered by Express.js and Redis, listens only on HTTPS now, currently using a self-signed cert, will have to play with trust authorities on the ionic side. Also at the moment server responds to `ALL` requests, cause it's easier to do testing with `GET`, will also set up unit tests in good time.
