Extend SceneJS.Scene to receive configs a la SceneJS.WithConfigs

Allow a configs object to be injected into the scene graph (like the one SceneJS.WithConfigs generates).

This is done by adding a fluent API style method, along with the same sort of thing for data scopes (like SceneJS.WithData generates):

var myScene = new SceneJS.Scene( ...);

myScene.withConfigs({ 
        "#myRotate" : {
              angle: 45

              "#myTranslate": {
                         x: 100
              }
        }).render();

The two types of data flow can work together - for data scopes, add a withData method:

var myScene = new SceneJS.Scene( ...);

myScene
     .withData({
            foo: "bar"
        })
     .withConfigs({ 
        "#myRotate" : {
              angle: 45
              "#myTranslate": {
                         x: 100
              }
        }).render();

Notes

• The render method will clear all injected data and configs.
• Passing in of data into the render method will be deprecated.
