added recruitment in minor settlements after researching the topmost (daemons) and bottommost (cultists) technologies for each champion of chaos respectively.

e.g. Valkia can recruit Bloodreapers in minor settlements if she has built the Bleeding Grounds and researched Honed Blades.
She can also recruit Cultists of Khorne in minor settlements if she has built the Ritual Hut and researched Insidious Selection.

this has not been added for Sigvald, since he has no technologies unique to him.
