Changes:
- adds 4 extra packs that use materials shared between the planets
- reorganizes the relevant part of the tech tree
- the planets share more materials between each other
- tech tree sanitation around the included planets.
- a hidden mechanic that acts as an "alternative foundation recipe".
- introduces some amount of "backtracking" to previous planets.

If Vesta is present then it will be treated as a "final planet" behind Aquilo.

Is compatible with organized solar system.

I'm receptive to adding more modded content to this area to make those mods integrate with space age better.

The science packs that seem to overlap with Dea Dia will move here when the rework on that is complete. Consider the Dea Dia ones deprecated at this point.
