Allow deconstruction outside visible chunks

[Burgled]

TL;DR

Let us mark things for deconstruction even if the items are not in a visible chunk, just as you can place blueprints outside visible chunks.

What ?

There was a change some time ago to allow blueprinting outside visible chunks but deconstruction was not included. I think this feature should be added to deconstruction to bring it up to parity with blueprinting. Currently it's convenient on a large map to construct rails by blueprinting and then waypointing a spidertron, the rest of the construction can happen without supervision. But deconstruction is much more tedious as the player must babysit the spidertron in map view since you can only mark things for deconstruction in the chunks currently visible to the spidertron.
