Changes made for Pathfinder 5226 controllers.

The 5226 has a section of magnetic memory that can save information even when the controller is powered off. The referenced status of an axis is one of these things. There is a problem though where if somebody chooses the wrong machine type in Pathfinder in which the axis on the machine has an incremental encoder and talks to the controller the referenced status could be cleared. If the correct machine type is chosen in which the axis has an absolute encoder then Pathfinder will be stuck in a needs reference state because there is no way to reference that axis on the machine. The only solution right now is to create a special build that will clear that section of magnetic memory and have it re-initialize with the correct machine type. The bug though is that the special fix was checked-in and released. This caused the reference status of axes with incremental encoders to lose their reference every power cycle because it was being re-initialized at start up.

The fix to this bug was to remove the special build changes from this release.
