[Modules] Need alert/notification when publishing items in unpublished module

[ibphysicsteach]

So, after several weeks I'm halfway through a chapter and have published a large number of worksheets and lecture notes for my students.  Finally today, a student tells me he can't see an item I just published--and sure enough, I forgot to publish the module for the chapter.  There should be an alert or notification when you try to publish and item in an unpublished module!
