Foldup sign (tiny change)

[aselpina]

Hi! I know that nobody cares too much, but it is such a tiny fix, that I feel like it is worth writing. I really like to design different signs and would love to see foldup sign working same way as barterstand banners (you apply an image on top of them rather then having it permanently in the recipe). It is also how it's working in real life, you put poster on top of the ready construction

+1 requiring to build in a sketch on anything shouldn't be a thing in the first place, IMO

Only challenge in implementing this should be the existing objects, optimally they would simply have the pre-existing sketch applied as removable object instead but no idea how much work that is, or if it's even feasible.

If that's the issue, this should very least be in the w14 preliminary changelog!
