Auto-smoothed cabling on maps (#38269)

* cable stuff

* colors

* Update cable.dm

* test wiring

* Update cable.dm

* Update cable.dm

* Update cable.dm

* Update cable.dm

* some mapping and tweaks

* Update cable.dm

* Update tgstation.dmm

* Update cable.dm

* rest of box

* so that powernets being set up works

* last grille

* some custom alignment of cables

* Update global.dm

* more specific directions for smoothing

* done mapping

* not a good idea

* should hopefully work

* Update cable.dm

* Update cable.dm

* Update cable.dm

* Update cable.dm
