Websockets in Chromium/Chrome

[pimotte]

While Firefox nicely responds to the websocket server (/api/ws) of the daemon, Chromium does not like it so much. There are at least two problems:

1. Chromium does not send basic authentication headers. This is being fixed from Chromiums side. See these two bugs.
2. The handshake does not complete. I'm guessing there is some sort of protocol mismatch between Undertow and Chromium, but I'm not entirely certain.

I'm not working on this until (1) is released from Chromiums side (it is now available as an experimental flag). If someone with more web-affinity wants to pick this up, feel free to.
