[JW Lua] Updating expression categories

[Aaron Sherber]

Thanks, Jan -- that does the trick. And that is indeed what I would call a
"weak link"! Looks like the same thing has to be done with positioning,
copying from the category to each expression that should be using it. I'm
guessing Finale must do the same thing under the covers when you make a
change to a category through the UI.

Robert, this smells like something that should be in the library, something
like category:resync_expressions() and/or expression.resync_to_category().
Do you agree? I'm going to need to add this functionality to my Options as
JSON script, so if you want it in the library I may as well make that part
of my PR.

Aaron.
