MIL-300 blog post enhancements

1. Add comment count to blog meta section just below the blog title (https://help.disqus.com/customer/portal/articles/565624-tightening-your-disqus-integration)
2. Blog post comment count should display on the blog list page at the bottom of each post. Similar to the implementation at blog.disqus.com. This comment count text should link to the blog post single page and scroll the user down to the comment section using #disqus_thread link. This should replace the "POST A COMMENT" copy that is currently displaying.
3. Date in post meta section should be formatted as MMM DD, YYYY (ex. Mar 20, 2014)
4. Post meta should read:
[comment count number] [bubble icon] [category link] > Posted by [Publisher First Name] on [Date]
5. Update the layout for single post pages so they are styled and formatted to look like all other post views (ex. http://milacron.crossroads.net/crossroads.net/2014/03/20/17092-prayer-request-3-20-14.html). I believe the jekyll layout on crossroads.net/app/_layouts/post.html needs to match crossroads.net/app/_layouts/blog.html
