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.
