[Radiant] New Blogging, Flickr and Spam-Prevention Plugins for Radiant

[Sean Santry]

With help in the past from some of you guys on this list, I've cobbled
together a few plugins for my site and thought others might find them
useful.

* BlogTags <http://seansantry.com/projects/blogtags> provides `next`
and `previous` tags for linking to the next and previous articles in
your blog and a `time_ago_in_words` tag to output the page's
`published_at` date in words (eg, "3 days ago").

* EnkoderTags <http://seansantry.com/projects/enkodertags> provides
tags to help prevent spammers harvesting email addresses from your
site. It's a simple refactoring of Dan Benjamin's Hivelogic Enkoder
<http://tinyurl.com/g54eo>.

* FlickrTags <http://seansantry.com/projects/flickrtags> is in the
*very* early stages of development. Right now the only really useful
tag is `slideshow`, which embeds a Flickr slideshow in an `iframe`.
You can see an example at <http://seansantry.com/portfolio>. I'm
working on integrating Scott Raymond's Flickr API
<http://redgreenblu.com/flickr/> for more advanced functionality.

Enjoy! And please feel free to let me know if you run into problems or
have suggestions for improvements.
