Power conduit visibility toggle button

[swizard]

I find it painful to keep having to click through the menu or click on a power conduit itself, a nice little button down the bottom left would be cool.

Click anything that is requires a connection to a power grid (including exposed wires themselves) and click on the Build copy button. It is literally 2 clicks (or 1 click and a tap on the O key) ;-)
