Changes made for Pathfinder 5226 controllers.

On some double folder machines the grippers are controlled through the hydraulics. Usually when controlled like this the pressure used to close the grippers can be adjusted depending on how tight you want the grippers to grip onto the material. Since too little pressure can make the grippers not grip tight enough and make the material slip out its good to have a minimum in case the user enters a bad percentage.

The solution was to create a Minimum Gripper Pressure parameter. If the gripper pressure entered in falls under this parameter then it will be changed to this parameter. Ensures the grippers will always have enough force to hold onto the material.
