Adds Bromuzl's custom item to item_defines.dm.
Changes labcoat code so coat buttoning isn't based on a giant switch, and icon states are set in the item itself rather than the logic for buttoning and unbuttoning.

labcoat_open is the icon state of the labcoat while open, and labcoat_closed is the icon state of the labcoat while closed.
Minor change for comments and defining the variables by full path.
Second fix attempt
No more sleeping in closets

Removes the 2-tick sleep cause by every closet in New().
Moves the code that sucks up items into closets to initialize() to avoid processing still null objects.
Shapely body bags.

Body bags containing bodies now uses a previously unused icon_state with a more defined humanoid shape.
All coats that can be buttoned are now subtypes of /obj/item/clothing/suit/storage/toggle

This includes labcoats, IA jackets, first responder jackets, and the brown leather jackets.

This way, code for button toggling doesn't have to be duplicated for labcoats and other coats, and it's easier to add other types of coats that can be buttoned up if someone wants.
Apparently the blue lawyer jacket didn't actually button up properly. Now it should button up, and uses the same system as everything else.
