[V3dot10] loading scripts via package universes

[Lex Spoon]

I do not like the change.  Package universes is about packages, things
that can not only be loaded, but also unloaded and compared against
different versions.  If we make a habit of loading scripts instead of
loading packages, then the PU will be unable to do a lot of its job.
It will be a step back to using file outs.

What are the concrete problems you are facing, Keith?  Let's find a
solution to them that is more package-like.
