Time-Green c04abab2bf [READY] Makes plumbing mappable and reworks hiding (#49644) 
🆑
tweak: Ducts can now be hidden under tiles
code: tile hiding is now an element and way cooler and sexier
/🆑

Ducts can now be hidden under tiles
Plumbing machinery connects can now be hidden aswell
Plumbing can now also be properly mapped in without breaking anything
Plumbing component now uses the normal overlay systeem instead of being a weird exception

You can now add the /datum/element/undertile element to instantly make something hidable under tiles when appropriate.
