Adamantine Golem rewrite stuff

still some stuff to do:
if you know how to do these let me know:

- [ ] give no eat?
- [ ] make it non gendered
- [ ] drop adamantine on death?
- [ ] remove blood splatters on ground and golem itself from hitting it or gibbing it
- [ ] make gibber gibs the proper color
- [ ] fix up blood colors or hopefully stop blood appearing altogether
- [ ] new brain type and sprite (golem core or something) or use the synthetic brain?
- [ ] give eyes? (it can see anyway)
- [ ] alter gibs to adamantine chunks
- [ ] no healing? - not sure
- [ ] denting instead of bruising - not sure
- [ ] no [BLEEDING] when damaged
- [ ] make non-injectable - not sure
- [ ] starting as one gives it more features such as eyes and i think complete organs - whereas spawning via rune doesnt
- [ ] fix all blood stuff (maybe just give alternate fluid instead of blood - or not)
- [ ] should it be able to eat?

You can probably give them different types of organs if you implement a new datum/organ/internal type as well as any functions in regards to them. But keep in mind you'll also need icons for them as well.
