Changes made for Pathfinder 5226 controllers.

The FoldGuard safety system has two initial setups that have to be performed before the machine can be put into production. They are the overrun test and the mute point set. To do these setups the FoldGuard laser needs to be clear so it can get good values. In some cases though the machine might have something attached that blocks the laser. In this case it was a shear attached to the lower bending beam. Since this machine was a double folder it meant the shear can be moved out of the way by moving the lower bending beam retract down. This will be forced to happen if the Overrun Test Active input is on and the machine has a shear. The controller will also attempt to move the shear out of the way in run when it can.
