Update traceroute list naming

[bjpetit]

What changed?

This change updates the naming of traceroute entries based on the number of hops towards and back.

• Instead of 0 hops, direct will be shown
• Pluralization of hop is handled in all cases
• If the hops out and back are the same, "x Hops" would be shown
• If the hops out and back are different, "x Hops Towards y Hops Back" will be shown

Why did it change?

This makes the description of traceroute items a bit more consistent.

How is this tested?

Ran through numerous permutations of traceroutes to ensure the naming was correct.
