Allows wirecutters to cut through spider webs (#5796)

## About The Pull Request
It takes 1.5 seconds for the web to be cut with wirecutters.
## Why It's Good For The Game
If you've ever been on a station with the duct spider trait, or just
gotten unlucky and had a duct spider vent clog you'll know very quickly
how unfun it is to clean up spider webs. Especially when using a welding
tool costs 1u of fuel per web. Making it less painful to clean up webs
from unchecked duct spiders will make dealing with them a lot better.
## Proof Of Testing
