Change data namespaces

[rosshadden]

• res.view.model should be the main data the view needs
• res.view.{{anything}} should be any extra data the view needs
• in debug mode, res.private should contain all keys on res.view
• res.view.public should be any data you want to be available to CS.public
• res.view([view], {key:value, model:{key:value}}, {public});
  • the first param in view is the path as always, which can be omitted
  • the 2nd param in the view is an extension of res.view properties, where one of them can be model which would extend the model
  • res.view({ foo: "bar", model: { sean: "clark" }});
    • {{foo}}
    • {{model.sean}}
    • it would extend any other res.view.model that existed in that res/req chain
