[1.05b1] Decouple world map and data from scenario

[Malevolence]

At the moment, world map and planet data are tightly coupled to the scenario binary serialization/deserialization.

Recommend that world map and planet data be decoupled into a predictable, separate data structure.

Structures involved with the world map and planet data should not "know about" scenario.

A decoupled, structure will allow for more options moving forward.

It will also give the scenario a predictable format, not subject to breaking changes from world building.

Yes, I understand what I am suggesting given the very brittle coupling with scenario elements like assets, etc.

This is, however, an investment in the future... like better reuse.
