Adds a simple to use [rss] shortcode with a couple of options:
<ul>
<li>feed, to put in the feed URL</li>
<li>num, to specify the number of items to show, defaults to 5</li>
<li>excerpt (true|false), whether to show an excerpt or not, defaults to true</li>
<li>target (defaults to none), to make links open in a new page (might break your html validity if under a strict doctype)</li>
</ul>
Example use:
[rss feed=”http://yoast.com/feed/” num=”10″ excerpt=”false”]
Or:
[rss feed=”http://yoast.com/feed/” num=”5″ excerpt=”true” target=”_blank”]
