Blogs now allow Commenting

I have now added the ability for users to comment on any blog article.

Authors of the article can delete any comment made to it, but only comment authors can edit the content.

As with blog posts, only the first 10 comments will load until you scroll to the bottom and then another 10 will load (and so on).

Comments will be ordered from oldest to newest. If you think it should be changed, please let me know along with your reasoning.
