OpenSSL Support for Ruby Module of Websockify

Integrated OpenSSL sockets into websocket.rb and tested against Ruby 1.8, 1.9, and 2.0.  Would not work in jruby-1.7.3.

I updated the echo.rb to accept command line arguments for the port, server certificate, and the server key.
I generated a self-signed certificate and key for testing.  I had to force Chrome to accept the certificate before it would actually perform the handshake during the tests.

I don't plan to push for jruby (or other implementations) unless you want me to.  It's in "good enough to use" state right now.
