Support for custom headers for handshake

Hi, please consider adding ability to add custom headers for handshake. In [RFC6455 ](https://tools.ietf.org/html/rfc6455#section-4.1) there one interesting point: > The request MAY include any other header fields, for example, > cookies [RFC6265] and/or authentication-related header fields > such as the |Authorization| header field [RFC2616], which are > processed according to documents that define them. I've found an example how to add custom header to handshake: https://blog.heckel.xyz/2014/10/30/http-basic-auth-for-websocket-connections-with-undertow/ but this is for Java and unfortunately isn't possible in HTML5. When searching over the net I found many places question about this option, for example: https://github.com/sta/websocket-sharp/pull/22 https://stackoverflow.com/questions/4361173/http-headers-in-websockets-client-api/4361358#4361358 https://github.com/aspnet/SignalR/issues/888 For example in Python this is possible https://stackoverflow.com/questions/15381414/sending-custom-headers-in-websocket-handshake. Other languages also support this. Last place missing is the browser. Please consider adding this into specification. Having this even as a draft would allow us to consider browser vendors to add support for it. If this is incorrect place for adding request about specification please forgive me and please point me to right place.
