Changes made for Pathfinder 5226 controllers.

A batch stop is a feature in Pathfinder where you can end the part creation at a certain step and return to the beginning. There was a bug in the controller for double folders where once it finished the last step before the batch stop it was not allowing the user to open the grippers and let the user move on to the next part. Essentially it was not acting as if it was the last step of the part like it should have been and was not releasing the part to the operator before going back to the beginning.

The solution was to have the step check if the previous step was a batch stop. This means the part was finished and we need to release the part to the operator. This allows the user to open the grippers and move on to the next piece of material.
