Move duplicant, morb, hatch, etc, en-route path off the floor.

Its hard to see this navigational path when its on a tile floor - it would or should be displayed similarly to that of the "show navigation" path - hovering over the tiles rather than directly on top of them. Either that or give it some color other than white.

I agree with this. Some additional thoughts:

- make the line slightly thicker.

- Color code the line based on upcoming path events. Red as it's passing through dangerous gas etc
