Title: Set the $_POST or $put_delete based on php://input on "applicaiton/json" request

When a request is sent as "application/json" (typical in backbone.js applications) rather as the standard application/x-www-form-urlencoded or multipart/form-data, the data in the header payload should be json_decoded and used as the request input.
