Updated JSON

Working JSON with subobjects
Example:

    {
        app: {
            title: 'foo',
            subtitle: 'baa'
        }
    }

added placeholder support for views Example:

    // Application_us-US greetings:
        'Hi {0}'
    // view.main.js
        title: { type: 'bundle', key: 'greetings', args: 'Customer' }
    // output
        Hi Customer
