If you check this box, it'll keep you in a mode where saving an alt style redirects you to the *next* one that needs labeling, until they're all done. Useful for big drops!
Just a little improvement to the form, so when there's no series name, the text field is empty—even though in most contexts we *pretend* it's "<New?">
We'll need this to fix up the series names and thumbnails for the new prismatic styles!
