rev d77ff0e is a workaround, which needs to be reverted.

Problem is that on data/templates/sidebar.html, formatsize retuns 0 as the json stats file has size: 0, from puppet ./modules/torrent/files/torrentjsonstats.py.

but puppet/modules/torrent/files/torrent-generator/torrent-generator is fine for http://torrent.fedoraproject.org

So we need to add again the ISO size, as a variable on this string, that needs to be translatable.
