Arachnid web immunity + crafting

[mnva0]

About the PR

This PR gives Arachnids the same spider web immunity that tarantulas get, as well as allows them to make webs from 1 silk. They take 6 seconds each to make

Why / Balance

I don't see too much of this going wrong balancewise. Not a PVP fork or whatever if that counts for anything, and this'd make having an arachnid crew or arachnid on your ship more interesting. Arachnids don't really have that much content aside from making some furnitures or cloth or clothing or whatever

I think this'd be a super cool thing to have for roleplay. An arachnid crewmember just claiming a small part of a ship and covering it in webs. Or people needing to walk through web-covered floors to even do business with some shady, untrustworthy arachnids

If someone smashes the webs, they'll be getting 0-1 silk back so constantly rebuilding is a bit of a pain if someone keeps tearing them down

How to test

1. Check to see that only arachnids have the recipe for spider webs.
2. self spawn:on MaterialWebSilk
3. Start placing webs, I guess?

it works mostly good, though of course there's that construction ghost jank you noticed on the discord... It seems to do with the iconsmoothing component that connects it with adjacent walls and webs. I don't think it should be an issue, at the least
