coiax 1c5b52b77f Refactors xeno eggs, and makes glowing resin glow (#25250) 
* Refactors xeno eggs, and makes glowing resin glow

🆑 coiax
add: Alien glowing resin now glows.
/🆑

Christ, all I wanted was to make glowing resin glow blue, like it says
it's supposed to.

Instead, I stumble onto the horrors of alien egg code.
First fix the spawn, then fix the icon states, then fix var edited burst
eggs, then make fully grown eggs spawned, then fix some weird use of
locate, rather than a var, then make the typecache spawn on initialize.

Should be no behaviour differences. Apart from the glowing resin.

* Art director light approval

* Code review and bug fixes

* I didn't know we had an "integrity failure" var
