* Fix Welding Tool Not Updating
- Added in the ISolutionChange interface so that it dirties the entity any time the amount of welding fuel changes. This applies whether it's lit or unlit.
- I also removed some redundant code.
* Update Content.Server/GameObjects/Components/Interactable/WelderComponent.cs
