Add robots variable to front matter

This is to ensure a robots meta tag is generated for the pages.
* Article 26 - because it has been removed
* Article 15 - because it is out of date
* chi, hkeype, menusbtn & sib - because they are obsolete
* cookies and software because I don't want them indexing
