JosJuice c8be819711 LogManager: Stop using manual memory management
This fixes a memory leak that would occur when the Android frontend
calls LogManager::Init more than once in order to reload settings.

Note that the log window listener is now owned by LogManager instead of
by the frontend, making it consistent with the other log listeners.
