Changes made for Pathfinder 5226 controllers.

There is a calculation for doing an adjusted load for small parts. If the backgauge is too close to the clamp to load at zero the backgauge will move to 5" to load then once gripped move closer for the bends. The gripper backstop offset was not being considered in the calculation which makes it easier to load closer to the clamp. The gripper backstop offset is taken into account when deciding if adjusted load is needed now.
