Client doesn't disconnect upon connection-loss

[Cyclone47]

When your connection (to the server) breaks the chatclient stays open and doesn't update anymore.
Need some sort of keep-alive ping to verify if the connection to the server is still available. -> If not, return to login form and show disconnected popup.

[Terrorblade]

We already send the keep alive packet, just need to set a connection timeout.

Setting missing in app.setting..

I have added a feature for this. I have tested this. I don't see why it would not work. Make sure your app settings is updated and if settings change no errors occur.
