title: Limit jekyll post list to certain categories
body: <p>I have a <a href="https://github.com/mojombo/jekyll">jekyll</a> website and I have a category (called <code>photo</code>) and I wanted to create a separate layout for a page that would list just the posts that were in the <code>photo</code> category. I also want to keep posts with the <code>photo</code> category out of the main index page.</p>
