Modified Files:
	exec/mqtt_spy.js
Log Message:
Add backup Ctrl-C input checking, just incase console.aborted isn't working

Telnet BINARY_TX mode from the client disables CTRL-C input checking in all
versions of SBBS (before now). This change shouldn't be necessary now, but
it worked-around the BINARY_TX issue when I was having it (couldn't abort
mqtt spy).
