Sorry about the whitespace changes

There seem to be three changes here

1. Adding a lot of logging
2. Changing ServicePointManager to TLS 1.2 only (seems unnecessary because something similar is already done in ForceEnableTLS method in Server.cs)
3. Changing SSLStream for secure websockets to use TLS 1.2 only

Seems like would be simpler to just change ssl.AuthenticateAsServer(cert); to ssl.AuthenticateAsServer(cert, false, HttpUtil.TLS_ALL, false); ?

1. Yes the logging helps the admin get the correct cert deployed. We should document the process of getting the correct type of cert.
2. I saw the TLS code in the other module but it didn't seem to be working.Also the Tls12 enums weren't available in Sockets.js.
3. Yes. We don't want to allow TLS 1.0 but 1.1 and later are OK. There are a bunch of options defined in the M$FT C# pages for AuthenticateAsServer but our compile system didn't recognize some of them. The one I put there works. We don't need the client to present or auth to us, unless we are going to a completely different level of authentication.
4. Changing the x509 routine to the one that doesn't need a password. For a public cert we don't want a password.
