bioluminescent kidan! 🐜 🏮 (#7137)

* bioluminescent kidan! 🐜 🏮

Gives Kidan an IC tab ability that makes them glow! wow!!!!!

This adds body and head markings, a new glowy organ to kidan lower body,
and glowing space ants! wow!!!!!!

Bioluminescence eats away nutriment, you can be glowing for some 13
minutes at roundstart before you starve out and the light goes out.
Dying also turns off the light. And shadowlings veil too.

Light color is based on a mix between head and body markings colors,
where the body markings color is slightly more predominant.

How bright you are depends on how much clothing you have. A full nakey
kidan is as bright as a flashlight, while a fully suited kidan isn't
bright at all. Rolling down jumpsuits makes you more bright too. Basic
idea is less clothes in the way, more brightness.

Oh you can also remove the light organ and implant it on other things,
and they will gain the ability to be bioluminescent. Yes you can be a
hot pink glowing neon green in the dark vulp. If you implant the organ
on someone else, the light will be based on the original kidan's colors.

kudos to Traveling Merchant for the sprite work, and KasparoVv for
helping me out with the markings part. Only one set of body markings is
done yet, but hey they're easy to make
