[MIRROR] Cauteries have heat, you can smoke with a space helmet [MDB IGNORE] (#23576)

* Cauteries have heat, you can smoke with a space helmet (#78122)

## About The Pull Request

Cauteries now have 'heat', like lighters, welders, etc.

You can smoke with a space helmet as long as you have internals on.

## Why It's Good For The Game

> Cauteries now have 'heat', like lighters, welders, etc.

> You can smoke with a space helmet as long as you have internals on.
