Patch (2886830) to allow a taller robot to detect shorter robots using the fiducial finder.

Hello everyone,
I've submit a new patch (2886830) that adds a new option to the  
fiducial finder.  I did this to get around the fact that a fiducial  
finder on a tall robot scans right over top of a short robot.

Summary of changes:
Adds a new flag to the fiducial finder, ignore_fiducial_zloc.  By  
default this is turned off and the fiducial finder works as it always  
has.
The default behaviour of the fiducial finder results in a short robot  
being undetectable by the fiducial finder on a taller robot.  This is  
because the ray traced out from the taller robot passes over top of  
the shorter robot.
With the ignore_fiducial_zloc option set to 1, a taller robot will now  
detect a shorter robot.  This is accomplished by adjusting the code so  
that a hit is detected even if the fiducial is lower than the finder's  
ray.
