check for existing session before starting newone

[shokarta]

so from time to time either app crashes, or it diwconnects me for network reasons and i normally should be able to quickly join back...
in browser cloud gaming its automatical, but not in your app.

would be good if you could check before starting a session if for this game session does not exist already.
I used to use it in my app, but not anymore and can not find proper endpoiont for this. so you need to sniff it from browser.

Yes, this can be optimized, and I have currently found a way to re-enable the session. This feature can be tested in future versions.
