Subject: [PATCH] Initial work on supporting the Winter.Blog plugin

Thoughts for further development:

We should add a Winter\SEO\Behaviours\SeoableModel model behavior that makes it easier to configure the meta data (meta, link, & structured data) that a model provides by providing configuration through model properties and standard getSeoDataAttribute() / setSeoDataAttribute() methods that can be overridden or just configured by the model properties.
