QoL heat pipe visual change

[kitters]

TL;DR

Heat pipes should light up with color when pointed with a cursor, like pipes.

Why?

One typically have a net of heat pipes on Aquilo. When rebuild, it's hard to see if different parts of it are still connected or not. I personally several times found chunks of my base frozen. The same thing with electric grid is not a problem, because cut off chunks are seen instantly. Cut off from heat chunks surprise you an hour later.

What?

The solution is highlighting a whole net when pointed wit a cursor, like pipes. Also may color gray if there is no heat source and red when there is one. Like pipes. Existing visual is not reactive enough, cut off parts are still hot and glowing for long time.
