Graduated base laws

I'll take a shot at some graduated laws here:

• Science - Research Prizes - Every 10 turns a random scientist from another empire (from their top science-producing systems) will for one turn offer visibility into their home system
• Science - Engine Tinkers - Fleets that have been disbanded for 10 turns can upgrade at a quarter of the dust cost (strategic costs are not reduced)
• Ecology - Farmers Markets - Gain system visibility and diplomatic status (strength of diplomatic relations with each major empire) for all minor factions
• Ecology - Soil Pre-seeding - New outposts mature immediately into colonies, and planets grow more rapidly to size 3 (Vaulters start at size 3, Vodiyani may not take this variant)
• Pacifist - Cultural Plays - Non-primary populations are much more likely to grow than the primary population. Random migration from other empires is much more likely. (Vodiyani and Umbral Choir may not take this variant)
