Changes made for Pathfinder 5226 controllers.

Pathfinder and the 522X series of motion controllers have a communication spec. that is used for setting up the machine and keeping the user in touch with what is going on in the controller through the UI. One of these commands in the spec. is a setup command for what an axis will be composed of. Things like feedback type, if there is analog control, what ports are being used, etc.

As a way of having better ability to add some new features to an axis a new field was added to this command. A byte has been added for Additional Options into the Command Axis Configuration 0x40C1. Each bit can be set for a new feature that can be handled by the controller.
