Because the app folder is signed as a whole, if any file changes the signing will have to change. This also means that if any file in Fiji.app is updated, we do not want to leave a .old version in the app folder as that will invalidate the signing. Instead, if we now detect any file in the .app folder is updated, we archive the complete state of the app folder to a single .old.app, and flag all files in the .app folder for installation/update.
