Excellent work figuring out that crash and how to fix it!
I also like the removal of Object in Layer, as I find that LayerManager fulfill that responsibility.
I've looked through the changes and I think they all look good. Feel free to merge when you're satisfied with the PR.

This fixes the crash reported over here on the forum. The crash was caused by the dangling pointer to the imported file’s
Objectdereferenced in the vector paint code in order to resolve colour indices.This PR completely removes
Objectpointers from the vector classes and instead passes the object as a parameter at paint time. (Tbh I’m also thinking about splitting out the painting code altogether, but I didn’t want to let myself get derailed.) It also removesObjectpointers from layer classes, which only used it in the constructor andsetObjectto generate layer ids, and instead passes those ids directly.Lastly, a proper colour import mechanism for vector layer import is implemented as well.
