EMCO Tool Turret / CNCPro "Pause" Input

I was not previously aware of the ability to assign the "ESTOP"
input as either that, or as a "PAUSE" signal, in CNCPro. Thanks to
Alan Rothenbush for the idea, and thanks to Doug Yeager for
implementing it....

This could easily be used to allow an output line to start the turret
motor turning, pausing other code executions, until the "PAUSE" signal
(returned by contacts controlled by the turret) is received.

The ESTOP functionality would not be impaired, since everything would
stop as desired whether as a result of an ESTOP contact or of a
PAUSE contact.

I can see how *I* could also use it to let me tweak a handwheel
or take care of some problem, without having to look for (and properly
operate) the Escape key......
