To answer your specific question, you can use MassNullEdit to purge batches of pages. However, that is the closest you will get to to forcing the update on all pages. In general, it doesn't take that long for the changes to take affect. If there are some key pages you are really concerned about, you can always just go there and purge them one at a time after making an edit to the navigation.
