Blueprints

Middenmoon has had multiple entity selection and copy/cut/paste for a while. The copied entities are pretty clearly just temporary blueprints. The obvious QoL improvement is to allow saving blueprints in a library.

Build A260222 has a first cut of the blueprint window bound to [B]:

Named books on the left.

Saved blueprints in the selected book on the right.

Clipboard history at the bottom with the last 8 temporary blueprints -- cut/copy/paste actions -- made on the the map.

To save a blueprint from clipboard history to permanent storage in a book:

1. Click to open a book on the left
2. Click the save button on a blueprint at the bottom
3. Click an empty slot on the right to place the blueprint

Save the game to persist changes. Blueprints are not limited to a single game -- you'll see the same books everywhere -- but the one save process covers everything.
