Don't install the included flag icons Debian already provides appropriate flag icons with the packages famfamfam-flag-(png|gif). Therefore ignore the images shipped by upstream.
Don't use the shipped static lists for the country-codes Debian already provides the necessary data as part of its iso-codes package. This patch changes the upstream behaviour to gather the data at runtime by parsing the XML files shipped with the iso-codes package. Translations for the countries names are also taken from iso-codes by using the symlinked .mo files with Django's lazy translation. Sorting function by Jakub Wilk.
