* Borrow page layout from About page and change CSS classes so names
  are applicable on both.
* Start using "mark" feature of Hyde to generate excerpts.
* Write initial content for the aside.
Add most popular posts.
Allow whole posts to show if no excerpts.

If no excerpt is defined in the blog post, show the whole post content
without the "Read more" link. Had to change Markdown formatting on some
recent posts to make this work.

If excerpt is present, append "Read more" link to it instead showing it
in a separate paragraph.

Replace element borders with hr where appropriate.
Add archive.
Increase the number of visible posts on blog home.
