[pmwiki-devel] Add guid tag to each item of RSS feeds

[Daniel Roesler]

Okay, here's a classic example.

I follow my pages and PITS entries via a wikitrail on my profile page
(http://www.pmwiki.org/wiki/Profiles/Diafygi), and I subscribe to it's
RSS feed (http://www.pmwiki.org/wiki/Profiles/Diafygi?action=rss). You
would think an RSS feed would notify you of changes to the pages on
that trail. But when Petko updated the PITS/01161, my aggregator
didn't recognize the update. I had no idea that Petko had updated the
page until I came back and checked the site. It created a huge time
lag between discussion/updates.

I've updated the PITS entry to include $ItemUnixTime by default so
there is no need for a new variable.

Avast!
