Ship design library

[ekolis]

Describe the feature you'd like to see
A library for ship designs, like FrEee has, that can be stored outside of a savegame and be reused in multiple games.

Benefits
Avoid having to redesign the same ships every game.

Describe alternatives
N/A

Additional context
Need to remember to prevent the player from building locked components/hulls that they don't have the tech or race traits for!
The library should go in My Documents\Stars! Nova.
The designs can appear as research results same as components and hulls.
