Recast: optimize and improve traverse link renderer
Only render the cross at the start as the reverse link will render the 2nd one. Else we render 4 crosses. Also made the alpha of the line around 50%, since we render the forward and reverse link, it will render with 100% opacity, if the reverse link is missing, the crosses will disappear and the line will only render at 50% opacity to make it more clear something is wrong.
