g8Scaffold improvement for multi-project builds

[enzeart]

I have a giter8 template that generates a multi-project build. The scaffolds are stored at the top-level .g8 folder. When I try to execute a scaffold in a subproject, it fails because it can't find the scaffold. When I move the .g8 folder to the specific sub-project folder, things start to work again.

Would it be possible to enhance scaffolding to look up through the project hierarchy for scaffolds, or is there some other way to declare scaffolds to work with multi-project builds?
