Proxy breaks with VSCode >= v4.10.1

[TobiasGoerke]

Hey and thank you for creating and maintaining this very useful plugin!

We've been using it for quite a while but noticed it doesn't work for newer VSCode versions.

Reading the proxy's log, it becomes evident it cannot open up a WebSocket connection. I assume this is due to VSCode requiring an origin header starting with VSCode 4.10.1.
You can even see it failing at "ensureOrigin".

As a temporary fix: using v4.10.0 works fine.

Thanks!

@xhochy @krassowski Has this been fixed or not? Can it be fixed?

I am running latest version of code-server without any issues. This issue is unclear to me as it mentions VSCode brand name but does not specify if it relates to usage of code server or openvscode server or an attempt to run vanilla VSCode which I don't know if ever worked well.
