server (websockets): fixed websocket handling on HTTPS connections: Original request used to retrieve a page was stored on dynamic pages, but after the end of it, the channel was deleted, resulting in a isSecure() always returning False, and troubles in chain leading to the the use of the wrong session object. This patch fixes this by reworking the way original request is used, and creating a new wrapping class allowing to keep an API similar to iweb.IRequest, with data coming from both the original request and the websocket request. fix 327
