Add meta properties via shortcode like syntax

Issue #5 new

Since the addition of the <shell/> switch, I think it would be better to give the user an option to embed meta data into any page via [[meta attr=val]] syntax. This would enhance the power of the search engine by giving it content to find without necessarily presenting said content to the user. The content could be presented if necessary via interpolated variable syntax {$attr} to output the "val" value of the meta property. And it would allow for catgories and tagging without having to create specific form fields on the edit screen.
