Changes made for Pathfinder V4 and V5.

Added Parameter 733 Clamp Laser Valid Move Delay

If the clamp is moving down and the clamp laser is blocked the clamp will be stopped. Once parameter 732 Clamp Laser Lockout Delay has expired a new timer will start based on this parameter. During this time frame the user has the opportunity to press the clamp down pedal to override the laser and move the clamp down in slow. If the timer expires then the operator will have to press the pedal to restart the timer, release the pedal and press again in the time frame. The system will not let the clamp come down unless this override is achieved.
