NOTE 2: The Crew Skills: Botany, Chemistry, Gastronomy,Geology, Medicine, Scavenging, Theft and Leadership don’t actually do anything,
they are just cosmetic, a separate script gives the gifts and makes it so
followers not count toward the crew total (for Crew Skill Leadership) so they
are all now capped at Rank 1.
