Moved plugins to root directory. I'm ditching the idea of shipping plugins with themes until it's more obviously necessary. This way it's easier to merge and update plugins.

+# Title: Simple Code Blocks for Jekyll
+# Author: Brandon Mathis http://brandonmathis.com
+# Description: Write codeblocks with semantic HTML5 <figure> and <figcaption> elements and optional syntax highlighting — all with a simple, intuitive interface.
+#
+# Syntax: {% codeblock [title] [url] [link text] %}
+#
+# For syntax highlighting, put a file extension somewhere in the title. examples:
+# {% codeblock file.sh %}
+# {% codeblock Time to be Awesome! (awesome.rb) %}
+#
+# Example:
+#
+# {% codeblock Got pain? painreleif.sh http://site.com/painreleief.sh Download it! %}
+# $ rm -rf ~/PAIN
+# {% endcodeblock %}
+#
+# Output:
+#
+# <figure role=code>
+# <figcaption><span>Got pain? painrelief.sh</span> <a href="http://site.com/painrelief.sh">Download it!</a>
+# <div class="highlight"><pre><code class="sh">
+# -- nicely escaped highlighted code --
+# </code></pre></div>
+# </figure>
+#
+# Example 2 (no syntax highlighting):
+#
+# {% codeblock %}
+# <sarcasm>Ooooh, sarcasm... How original!</sarcasm>
+# {% endcodeblock %}
+#
+# <figure role=code>
+# <pre><code>&lt;sarcasm> Ooooh, sarcasm... How original!&lt;/sarcasm></code></pre>
+# </figure>
+#
