json-schema: add support for Rich Results: Json schema for structured data (#36)

Browse Source 
* json-schema: init

* sameAs can be set through .Site.Params.schema.sameAs
* if it is not specified but social-icons exsists, we use social-icons for sameAs vars
* .Site.Params.schema.sameAs overrides social-icons
* publisherType can be changed via .Site.Params.schema.publisherType
