[JW Lua] Set staff to chromatic transposition

[Aaron Sherber]

I also don't fully understand why, for example, TransposeInterval changes
when TransposeChromatic gets set -- *before* calling staff:Save(). Isn't
this just manipulating properties on an in-memory object at this point? And
there shouldn't be any interaction with Finale until the object is saved?
So is something funky going on with the PDK Framework class?

Thanks,
Aaron.
