Improve meta description

Rather than use the same description on every page, prefer the post summary if it's available and only use .Params.description on the root page. This mimics the behavior of the [opengraph internal template](https://github.com/gohugoio/hugo/blob/master/tpl/tplimpl/embedded/templates/opengraph.html#L2) for the `og:description` tag.
