How to: Get rid of old ship designs?

[Suicide Junkie]

Since SE3 or before.

When there is no longer any need to know the design, it is deleted.

Design plans are needed if:
- The design is not obsolete, and might be used in the future.
- There is at least one ship of that design floating around the universe.
- Another race has the design in their "enemy ship designs". In SE3, an enemy ship design was forgotten after 50 turns of not seeing it, either in combat or via LR sensors.
