Cross-round blueprints

[Superlagg]

New feature: replace the ABC-U with one that I know what it does.

Also, does it need exposed space tiles to work? That's what the wiki says. Can it be used to just place or replace furniture? Cus it'd be great to have a rapid redecoration device.

Unless it already does that. Maybe I should ask questions about things before charging in demanding changes to things that are already the thing I want it changed to.
