[Patch 2/2] org-publish

[Manuel Giraud <manuel.giraud@univ-nantes.fr>]

This second patch (that should be applied after the first one) adds a
formating option to sitemap entries. One can now use a formated string
to generate a sitemap entry. This formated string currently understands
title (%T), author (%A) and date (%D).
