Support for SSL

[jussimalinen]

There should be support for SSL including client side certificates and various SSL/TLS versions.

I would like to create server something like this:

Start SSL Server 127.0.0.1 443 name=MyServer
... protocol=Example keystore=ServerKeys.pem
... sslversion=TLS1.2 ciphers=something

I would like to use client something like this:

Start SSL Client name=MyClient protocol=Example ca_keys=ServerKeys.pem
Connect 127.0.0.1 443 client_certificate=ClientKeys.pem

there is a new branch where work has been started.
