Deconstructing walls without repairing them (#6094)

# About the pull request

You now need to have disarm or above to slice through walls, and help
intent to repair walls.

# Explain why it's good for the game

Comtechs now don't need to spend 30 seconds repairing a wall, waste like
5 units of welding fuel only to deconstruct it. Now you can have choice
in what you do! :D
