Title: Fixed passthrough creation so that variable trees are deepcopied as they should be.

This fixes a bug reported by Andrew Ning on the Q&A forums.

When create passthrough copied a vartree, it was not doing a deepcopy. I fixed this so that it performs the kind of copy requested by the trait's metadata. Slots are always set to "deep" copy.
