Richard Stanway 5182368009 UI: Properly handle SIGINT on non-Windows platforms ...

Running Qt code in a signal handler is not safe. Per the Qt docs, we
instead create a pair of sockets and a QSocketNotifier so that the
signal handler can notify the main thread which can process the exit
request without risk.
