    [download] set the content type to activate the gnome-theme-installer
    
    Set the content type when downloading gtk, metacity or icon themes to allow
    the browser to open the file in the theme installer. The extension is also
    checked because the application/x-gnome-theme-package type can only be set
    if the archive is gzipped.
