Set HTTP headers Link, X-Robots-Tag

[woto]

Hi, I've found your gem and it seems structural and handy instead of scattered @seo_title @seo_description etc... across code base. But I found one thing that worrying me. I use sometimes HTTP headers (Link: ... rel="canonical", Link: ... hreflang="...", X-Robots-Tag: ...) instead of meta tags. I'm not a SEO guru. But I think it is more "faster" way to tell to the crawler (without parsing html step) furthermore it supports cases for example with rendering pdfs etc....

What do you think about this feature in this gem?
While waiting the replay I'll look at the source code ;).
Thank you.

Kind of tricky to implement in the current codebase. The main configuration is in the layout file, at which point it might already be too late to render headers (with streamed rendering, for example). I will think about how this can be solved...
