    Treat a download size of 1 as a special value
    
    Web apps don't require you to download anything (the icon is already
    downloaded by the time you're looking at the app's details page).
    However we can't just do "gs_app_set_size_download (app, 0)" because 0
    is treated as meaning "size unknown" which shows up in the UI as a
    question mark. So allow plugins to set the download size to 1 byte as a
    way of saying no download is required.
