Added new plugin to list categories in sidebar.

Using http://www.dotnetguy.co.uk/post/2012/06/25/octopress-category-list-plugin/,
added new Jekyll style plugin to list site categories in the sidebar along with
a count of the postings in each category. The category name is a link to the category
page where all the postings are listed.
updated _config.yml to use new custom aside for categories
Corrected category tags by eliminating trailing commas.
