[Router] Update the request object with parameters of the route

[vincentdieltiens]

Update the Url QueryString of the request object with the parameters return by the UrlMatcher to let the developer access thoses parameters.

The user can simply access the parameters via the Query String of the request object :

public function onOpen(ConnectionInterface $conn) {
    print_r($conn->WebSocket->request->getQuery());
}

fixes #141

cool! Would you mind adding a unit test to RouterTest before I merge this please?

[vincentdieltiens]

Ok, I will try to do that ASAP :)

[cboden]

Any chance of that unit test incoming @vincentdieltiens? :)

[vincentdieltiens]

You're right ! I still do that. I put it in top of my TODO list ;-)

[cboden]

Should probably also add _format and _local I think. Or perhaps just ignore all starting with a _?
