ISSUE #542 - detect if SSL is in use, and adjust the websocket URL to…

… match (either `wss://` or `ws://` for non-TLS).

The URLs to forward are:

* /websocket/ws (the main "ticker")
* /websocket/private_ws (for per-instance data feeds) - there's nothing actually "private" about it, it's "session local".
