[WIP] Improve Game Room Management on Server

[xeruf]

Should fix #201 when ready.

It is currently planned to implement the Lobby in a Kotlin Actor pattern to prevent threading issues and improve single responsibility.

[Coronon]

When will this patch be ready? We are trying to train our AI but the Server just keeps failing after around 120.000 or so moves. This build is failing for us:

java.lang.Exception: Server terminated unexpectedly!

[xeruf]

I'll look if I can find a preliminary fix, this PR will unfortunately take a bit.

Unfortunately the Stacktrace is not really helpful here. But why are you even executing the tests of the socha repo? I don't see why you would need to do this.
