Logging system does not work after first Play Mode run

[qdot]

If Play mode is run more than once, all runs after the first will not show log messages. This is due to the FFI system not handling clearing the static logging global, and our inability to pass a logging guard system in the FFI currently.

Logging should work for game processes, this is only a play mode bug. Also, if the system is using the external executable, logs can possibly be saved out from there as a workaround until this is fixed.
