Fixed server hanging on stop

[Zeejfps]

Added a listening flag to control the infinite loop in the listening thread.

Inside the loop I am using listener.Pending() to check if any new clients are ready to connect to avoid the blocking Accept call that would otherwise freeze the thread preventing Thread.Join from being used to gracefully terminate the thread.

When the flag is set to false, the while loop is exited. This allows for the listener to be closed on the same thread it was created avoiding the WinSock exception that was being thrown.

Failes the IPv6 test, but I think this is due to the test being incorrect?

I need to make another push that will fix the Repeated Start Stop Test.

Edit: Done

so just to be clear, even though we call .Interrupt(), it does not end your listener thread?
that shouldn't happen at all

Yes i rand the code from issue #72 and it froze on my windows machine.
Strick firewall settings were in used, but I do not see how this would prevent the server from not being able to terminate.

sorry, didn't have time for telepathy in a while.
can you confirm that the issue still exists in the latest version?
did a major rewrite in 2021 :)
