Adds hauntium as a reagent with new fun uses. (#77471)

## About The Pull Request
Adds the material hauntium as a reagent, along with bringing some unique
effects with the reagent.

There are a few new ways to get it other than just the camera obscura as
before, such as grinding certain ghostly things.

Unique effects it brings:

- It works in metalgen (I believe the metalgen recipe is still broken as
of making this) to make hauntium infused metalgen.

- Any object touched by the chem will temporarily have the haunted
effect, letting it teleport around randomly and even attack people.

- If you put it in your body, it hurts your "soul" (soul being heart and
mood)

...unless you are morbid or undead, in which it gives a slight mood
boost and acts like an addiction-less drug
## Why It's Good For The Game
Hauntium previously was super niche and not very useful other than
making funny haunted toolboxes from it. This expands it's usage and
makes it a lot more interesting. I also know a good few people who have
also wished this was available to use in metalgen and now you can!
## Changelog
🆑
add: Lets you grind things into a hauntium reagent which works similarly
to the solid form but is versatile and has some unique effects.
