Fix edge case where aiEnabled bots ignored threat score spawn conditions and spawned in the wild. They should now only spawn around settlements

Fix: Prefab AS2-Portahut-Crew Y Offset #57

* 18 New encounters, including mines, workshops and towns
* 60 New Prefabs including some of the new Warfare blocks
* Replaced blinky antenna signals with GPS coordinates, this helps keep your screen clearer and improves battery time
* Optional AiEnabled Integration (requires AiEnabled mod) - spawns bots to defend settlements
* Better DNSK support (requires Daily Needs Survival Kit mod) - spawns food and drinks loot
* Improved loot balance with better progression - even if you're stranded miles from anywhere you should be able to salvage enough to survive.
* Added Admin options to prevent turrets spawning and add more loot
+ behind the scenes improvements to allow future expansion
