| Subject: | patch with tweaks for rss 2.0 |
added support for self-contained items (i.e. no outside link- all information contained in the description). the spec allows the 'link' and 'title' to be optional if the description is present. i have a few feeds that do not have links and adding fake ones would only confuse the subscribers of the feed.
also added a 'guid' field, which is the equivalent of isPermaLink="false"
