Adding the option to use canonical tag

[orelby]

There are people who might want to publish in this website tutorial series (only the introduction or something like that), but still to publish them in their blog (or somewhere else) without harming their blog's SEO (or this website's). I know that I want that option. Maybe other people also want this ability. I would have written it myself (and I don't think it's complicated), but I don't know anything about YII. I use Laravel... Thanks in advance. :)
