Changes made for Pathfinder 5226 controllers.

Jorns Twinmatic machines have two different kinds of grippers. One is called the sheet gripper which is used most often for production and a flange/alternate gripper that is used for gripping over a flange and/or hem. On some machines these grippers can be split up into zones to be able to use them separately. As in the one set will be opened and closed with a gripper pedal and the other set of grippers will be opened and closed with a different gripper pedal. This is done with separate I/O for each zone to control the grippers. Having zones was implemented for the sheet gripper previously, but not for the alternate gripper.

The solution was to add the ability to split the alternate grippers into zones like the sheet grippers. This gives separate control of the alternate grippers.
