Search Servo Initialization Caution

Note that the pan servo pwm is hardcoded to zero. If you have changed PAN_MIN_PWM_DEFAULT from zero to something else then hardcoding to zero is incorrect. Change the line to:

 temp_pan_servo = Tracking_Config_Data.Pan_Min_PWM;

Hmmm... I wonder what the heck I was thinking when I did that? Oh well, since I can't possibly explain this away as an undocumented "feature", I guess we have to call it a bug <grin>.
