Updating schema.org web pages re: RDFa lite 1.1 and JSON-LD support

It may be helpful to:

* update references to forthcoming RDFa support which now exists
  * http://schema.org/docs/faq.html#14
  * http://schema.org/docs/gs.html
* feature prominent code examples on the very first index.html page of
http://schema.org
  * add RDFa 1.1 lite versions of the getting started examples
  * add JSON-LD versions of the getting started examples
  * add Turtle versions of the getting started examples

God love James Cameron.

Where are the sources for these pages?
