Vendor Books (AI Core 5%, Ancient 10%, Engineering 10%)

Adds rare spawn chance for the following items in any vendors stocking construction items.
AI Core = 5% chance
Ancient Science Book = 10% chance
Engineering Research = 10% chance

Other mods on the workshop do similar things, one adds Ancient Science and Engineering spawns to vendors, and another mod adds AI Core spawns at much higher rates, and alters squad templates.

I made this for myself because i wanted one tiny mod that added all items at once, with no other changes, at lower spawn rates.
