Add blog archives functionality
The blog at its current state isn't much functional. I was missing a blog archives page, so I gave it a go.
At the front blog page there is the excerpt of the last post and right under it a list of the last five posts. A link to the archives page is also provided. The link to the archives is also right after every post ends and before the newsletter block. The archives list has the posts separated by year. The pagination links were removed as they are pretty much useless now.
