Rubble walls should be hammered easier and or dug by shovel

[Frosty_Mentos]

Since it's less of a wall and more of a bunch of rubble I feel like it's unnecessary for it needing more hammerings than one or two. Would give us easier way and less time on dealing with all of them where you don't want the walls.

Or have shovels to dig up the rubble instead? Kinda would make sense than hammering a pile of rocks.
