Static page content loading support added.

I just added loadContent method and related helpers to view’s class for
loading predefined or pre-rendered DOM elements as a page.
String content and mixed page type supports added.

Raw string loading added to view.loadContent method. Mixed page type
support like generated page -> loaded page -> generated page -> loaded
page -> generated page -> generated page added.
Example usage added to my-app.
