Preserve host and port number when connecting to backend via websocket

[pun-ky]

it is interesting because logging in works when CB is deployed on a different port number.
however, doing any other stuff like changing some board title is not working in that case:

please fix it to make that tool more adaptable in various deployment options.

how about extracting the current port number right before requesting ws://localhost to update it to ws:localhost:8099 as in my case? by using JS and browser API (window.location.x) it seems that it is easy to do...
