LemonInTheDark 24326bc649 Hud Image Culling By Z Level: Theft edition (#65189) 
* makes hud images only apply by z level

* makes some of the atom_hud procs have better names

* fixes warning with the hud_user list and adds better documentation

* better docs for hud_images

* removes TODOs

* docs for hud_list

* adds support for linked z levels so mobs can see lower ones

* fixes merge conflict and shittily makes only shocked airlocks get added

* adds support for setting images in the hud as active and inactive

* gets rid of unatomic spatial grid change

* maybe i should actually try COMPILING my changes

* fixes merge skew and makes it compile again

* fixes huds refusing to remove from users who changed z level

* improves z level and registration logic

* fixes antag huds not appearing

* Fixes antag huds not properly setting. We now use hud_list in init, so it needs to be set before the new call, not after. Not sure why the use of appearance key was split like this, but none else knows either so none can stop me

* Ensures that hiding a basic appearance also hides the atom's active list too

* Fixes antag huds going poof

Ensures that remove_atom_from_hud will return false if the passed atom
isn't managed by it

This fixes antag huds disappearing randomly, since they assumed that if
the parent call of remove_atom_from_hud returned true, we should delete
ourselves. This is a safe assumption for them to make, since they should
only ever have one atom.

Does kinda bork if we call remove_atom_from_hud in a way that is unsure
if the passed atom is actually in that list. We were forced into doing
this by how atom huds use the qdeleting signal.

* makes basic alternate_appearance's only update themselves when setting their hud image to active and makes them not add themselves to the global huds_by_category list

* fixes mistake with hud_users list being set non associatively (bad)

* as anything in bot path loops

* Fixes merge skew problems

* Makes bot paths non global

This way they can show themselves to only the bot that "owns" them, ya
feel me?

* Fixes huds not showing up sometimes, cleans up some code

Post Kapu's limb refactor, we were calling prepare_huds twice in a human
init call chain. What was happening was this:

call prepare_huds() // Human
I gained a new hud image
I set active hud icons to mirror it
call prepare_huds() // Living
I overwrote the new hud image
I attempted to set active hud icons, which failed because it assumes
this can never happen

*cries*

* Renames add_hud_to_atom to show_to

My hope is this will make understanding hud code a bit easier, by tying
the behavior to a "verb" more closely. Also renamed a few vars

* remove_hud_from_mob -> hide_from

* Nitpicks a few comments

* Whoops/fuck/shit/damn it all/hhhhhhhhhhhh

* Moves check down, improves stack trace a bit
