In [Atom](http://www.ietf.org/rfc/rfc4287.txt), we can provide `published` and `updated` information.
In [RSS](http://cyber.law.harvard.edu/rss/rss.html), there is only `pubDate`, for the 
publication date, but an update can be mentioned with the [`dc:modified`](http://www.ietf.org/rfc/rfc2413.txt) 
element (whose datetime format is [iso 8601](http://www.w3.org/TR/NOTE-datetime)). 
This patch updates :) `inline.pm` and the two relevant templates.

> I tested a slightly modified patch, which I've put below for now.
> feedvalidator.org complains that dc:modified is not a known element. I'll
> bet some header needs to be added to make the dublin core stuff available.
> The atom feeds seem ok. --[[Joey]]

   * Updated French translation from Cyril Brulebois. Closes: #437181
   * The toc directive doesn't work well or make sense inside an inlined page.
     Disable it when the page with the toc is nested inside another page.
+  * Apply a patch from NicolasLimare adding modification date tags to rss and
+    atom feeds, and also changing the publication time for a feed to the

>> Yes I noticedthe bug today; the correct (tested on feedvalidator) rssitem.tmpl template must start with the following content:

    <item>
        <TMPL_IF NAME="AUTHOR">

        <TMPL_ELSE>                                                                
        <title><TMPL_VAR TITLE></title>                                            
        </TMPL_IF>

        <dcterms:created><TMPL_VAR DATE_3339></dcterms:created>                    
        ....
 
>> and rsspage.tmpl must start with:

    <?xml version="1.0"?>
