Linux process doesn't terminate on exiting the launcher

[jdrueckert]

Expected

Clicking on "Exit Launcher" results in launcher closing and terminal process terminating.

What happened

On clicking on "Exit Launcher" the launcher window closed, but the terminal process kept running.

Additional Info

OS: Linux Mint 18
Launcher Version: 4.1.1

How to reproduce

1. Start the launcher (run in terminal)
2. Configured it to not close on starting a game
3. Start a game
4. Exit the game
5. Click on "Exit Launcher"
6. Observe in the terminal, that the process doesn't stop.

I'm having trouble reproducing this when running from source.

But if it's related to the game runner thread — and it probably is, if it only happens after starting & exiting a game — it might well be fixed by #571.

I can't reproduce this as well. A freshly downloaded 4.1.1-Linux64 build exits as expected on my arch linux. Could this be a ubuntu/mint issue?

Exits fine for me as well - I think the underlying problem is the game process not closing properly, I've create MovingBlocks/Terasology#4240 to track that.
