* Turns stickers into a component and an element (#74091) ## About The Pull Request Adds /datum/element/sticker, and /datum/component/attached_sticker Sticker items now mostly operate off /datum/element/sticker The sticker element, hooks the whole "attach to stuff" and adds the attached_sticker component to its target The attached_sticker component, adds the overlay, hooks the clean and on-fire signals. ## Why It's Good For The Game Allows to check if a sticker is present on an object (which I will use later) Code is probably cleaner??? ## Changelog 🆑 refactor: Stickers use a component and an element now to do their sticking /🆑 * Turns stickers into a component and an element --------- Co-authored-by: jimmyl <70376633+mc-oofert@users.noreply.github.com>
