Websocket support

[bluppfisk]

While using my phone hotspot the other day, I noticed how much data the REST API takes with 5 tickers and 3s refresh rate: constantly pulling at 10-15KBps. Websockets should minimise the amount of bandwidth.

Coincidentally, I'm doing a lot of websocket dev at work so it's fresh on my brain. I'll take a look when I have some spare time

at the moment I have very little time to work on this project so I would very much welcome any contribution. You can check out my 'websocks' branch where I got something rudimentary going. But the issue is getting it to run properly (and reliably) in a GUI environment. If you have any ideas on that, I'd love to try and implement!

hi @chrisplusplus ; have you ever looked into this? Kraken is soon supporting Websockets so it'd be fun to integrate it
