WebSocket transport

[ecorm]

WebSocket++ could be used for this. Wrappers compatible with the Transport and TransportBuffer concepts would need to be written.

Seeing all the tidyness of this project (love it!), I can't help but think that the title of this issue should spell Websocket as WebSocket, with a capital 'S' :)

There. Fixed! :-)
But I'd rather complete and close this issue, than fix spelling errors. I've been really busy at work, but I hope to able to spend more time improving/completing CppWAMP in the new year.

Oh come on, you already fixed the issue title. You're halfway there! Sit back and admire your work by the Christmas tree :)

I'm now preferring Boost.Beast over Websocket++, the former providing HTTP support that would eventually allow me to implement a REST bridge similar to that of Crossbar's.
