pages (blog/atom.xml, u/atom.xml): Atom feed implementation:

- Content-Type is set to suitable value
- common/blog is used, comments are disabled
- request_uri, http_uri and xmpp_uri are set in template data
- "updated" variable in template date is set with the "updated" value of first item (i.e. the most recent one), or to current time if there is not item yet.
- u/atom.xml us a simple redirection to blog/atom.xml
