Added the comments system

JavaScript is used to pass comment data from a form to a PHP script. The
php script will perform validation and store the comment in a database
after performing sanitization operations.

The plugin is used during the wintersmith build process to make the
comments available to jade template files so that they may be added in
the final output of article html pages.

Markdown rendering is used during a comment preview, if the user wishes
to see how their comment will appear after it is published.

Added url alias php script

Whenever a url is changed, the old one is saved in a database. A
redirect to the new url will occur if users use the old version. This
ensures that links will never break.
