Add unsaved files warning to VCR product edit pages. If you edit the files on your product (uploading, re-ordering, removing) some text will pop up to remind you to save, and if you try to navigate away from the page (refresh, back button, close tab, etc.) you'll get a pop-up warning about the unsaved file changes. This only applies to file-related changes!
