Canonical Link to the Original Source for Republished Posts
Points the canonical tag of a post to the URL in its "original_url" custom field, for articles first published elsewhere, so the original keeps the search credit.

SEO Title, Description and Noindex Fields
Adds a small SEO box to the editor of posts and pages with a custom title, a meta description and a "hide from search engines" option, for sites without an SEO plugin.
