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.

+# Outputs a span with a data-pullquote attribute set from the marked pullquote. Example:
+#
+#   {% pullquote %}
+#     When writing longform posts, I find it helpful to include pullquotes, which help those scanning a post discern whether or not a post is helpful.
+#     It is important to note, {" pullquotes are merely visual in presentation and should not appear twice in the text. "} That is why it is prefered
+#     to use a CSS only technique for styling pullquotes.
