Should load external content into a page using source and trigger sourceLoaded event

[finnsson]

<div data-bind="page: {id: 'lorem', source: 'lorem.html .content', sourceLoaded: loremIsLoaded}"></div>

The source can contain a selector (see .content above) in order to extract a fragment on the site.
In the example above loremIsLoaded is a function that is triggered after lorem.html is loaded.
