Allow wizards to turn dead players into skeleton minions

[slarticodefast]

About the PR

Requires #43701 to be merged first
Adds a wizard relic purchaseable from the grimoire. When used on a dead player it will gib them, spawn a skeleton and transfer the player's mind to it.

The item is basically the same as in SS13. The name and sprite were taken from citadel station.

Why / Balance

Follow-up to the PR linked above. Emo brought up a lot of good points in that PRs decription on why closet skeletons are causing problems as a free antagonist and should be removed. But since I like the sillyness skeletons bring to the game I think this is a good way to keep them as a feature in a more purposeful way.

Skeletons should probably also be nerfed a little from a combat stats perspective, see #43711

Technical details

Spawns a new mob and transfers the old player to it, while gibbing the old body.

Added a missing filter check in the client-side PopupCoordinates that caused it to be ignored.
Removed a mistakenly added tag from the wand belt's whitelist that allowed it to hold any chameleon-copyable clothing item.

Seems cool but three charges might be a bit low

I'm pretty sure you can use the recharge spell on it

Unpopular as it might be, Smite spell will always hold the number one spot as my favorite spell.
This however, is definitely a close second!

3 Wizcoin equipment + 1 Wizcoin spell (recharge) is standard and commonly bought combo.

• Item is powerful enough for its cost, doing something similar of other 3 costs: (Smite and Cluwnification)
• Keeps victims in the game from completely loathing the Wizard. (You serve the Wizard, and can play the game still!)
• Pairs well with other equipment, since Recharge is equipment focused.
• Repurposes old content, while still making it feel like its dealt with in the same way!

This comes with the '"""downside""" of Skeletons always being valid now, as they are extensions of the Wizard.
But all of the Skeleton bickering usually came from the dreaded 'Free Agent' status. Giving a much clear focus on their allegiance will hopefully stop this!

Skeletons being thralls means that death isn't ALWAYS the end for the Wizard, as they can now help bring them back as well!

Hello, I am back after reading #43730.

Seems cool but three charges might be a bit low

I have to agree with YoungThug.

After seeing the new approach to the skeleton. These thralls have been re-contextualized in the role they serve. They feel more disposable, 3 charges for pre-nerf skeletons was completely reasonable.
Post-nerf? 2x damage from blunt sources is BRUTAL. All it takes are some vigilant passengers with toolboxes.

Sure they can grab armor, they have flash resistance and are space immune, and have 2 hands, they are by no means defenseless. But their disposable nature and association with the Wizard cannot be ignored, most people are willing to spend a few moments to stop something that could snowball into something catastrophic down the line if left ignored.
(see Xenoborgs)

It having the benefit of being rechargeable is good, you can in theory have unlimited skeletons. But raising the capacity to have the item stand on its own is important. If someone wants to buy the stone on its own without the recharge spell to save on 1/10th of their budget, they are spending 3 Wizcoin on 3 charges. That is a scam, and its over-reliance and expectation to have you buy another spell is not good!

The stone should be able to hold up on its own as a purchase, this combined with the species tweak I think you should raise the capacity to be higher.
Maybe 12 charges? (4 per 1 Wizcoin, for 12 total?)

Wizard now conversion antag.
