## About The Pull Request
- Rewrites how action button icons are generated.
- Prior, generated an action button icon was fairly simplistic and
didn't allow for many changes. Someone recently added the option for
overlays to be generated over action buttons, but the framework was very
weak.
- Now, action button icon generation is split across multiple procs,
like atom icon updates.
- The background of action buttons are underlays
- The actual icon of the action button is the icon and icon state of the
action button movable
- The rim / border of the button is an overlay, layered overtop the
button.
- Allows observers to see what action buttons a mob has. They even
update in real time! And no, the observers cannot click on them.
## Why It's Good For The Game
- Runechat text of action buttons are no longer hidden behind the actual
icon. This was very ugly with cooldown actions, as the cooldown text was
hidden behind a lot of spell icons.
- Cuts down on a lot of icon duplication.
- Gives much finer control over action button icons
- Saves a bit of processing from generating full action button icons
when not necessary. Not implemented in many places, but is in some.


## Changelog
🆑 Melbert
add: Observers can now see what action buttons an observed mob has. No,
you can't click them. And no it doesn't show EVERY action.
refactor: Refactored how action button icons are generated. Some actions
will now use a colored border when active instead of just turning green.
Cooldown text will also appear on the top layer of actions too. If you
see any funky lookin' icons (namely their borders), let me know.
refactor: Bluespace Golem's teleport action is now a cooldown action.
fix: Construct actions go to the middle of the screen like expected.

About The Pull Request
Converts more inputs to TGUI. Possibly all user-facing input lists in the game.
Did any surrounding text/number inputs as well
Added null choice support so users can press cancel.
Added some misc TGUI input fixes
Fixed custom vendors while I was there
I refactored a lot of code while just poking around.
Primarily, usage of .len in files where I was already working on lists.
Some code was just awful - look at guardian.dm and its non use of early returns
If there are any disputes, I can revert it just fine, those changes are not integral to the PR.
Why It's Good For The Game
Fixes#63629Fixes#63307
Fixes custom vendors /again/
Text input is more performant.
Part of a long series of TGUI conversion to make the game more visually appealing

Fixes#62643
Fixes aux-base turrets from hard-deleting by handling their deleting on the aux base itself.
Converts the turrets list to a proper lazylist and cleans up some surrounding code involving the turrets list.
Also fixes a copy+paste error with tiny fans being placed.
Converts most spans into span procs. Mostly used regex for this and sorted out any compile time errors afterwards so there could be some bugs.
Was initially going to do defines, but ninja said to make it into a proc, and if there's any overhead, they can easily be changed to defines.
Makes it easier to control the formatting and prevents typos when creating spans as it'll runtime if you misspell instead of silently failing.
Reduces the code you need to write when writing spans, as you don't need to close the span as that's automatically handled by the proc.
(Note from Lemon: This should be converted to defines once we update the minimum version to 514. Didn't do it now because byond pain and such)
