Rename Pass-Thru Cable and Pipe

[elenya-grant]

This came up in PR #555 in this comment which says:

maybe change the names of pipe and cable to something that indicates their "pass-through" natures, such as pipe-passthrough and cable-passthrough

cable and pipe are "protected" technology names in H2I - but as more transport components are added, it may be good to rename the "protected" technologies to something more specific.
