docs(guide/overview): Refactor overview and mvc docs

Before, there we multiple overview docs:
- guide/overview
- guide/introduction
- guide/dev_guide.mvc
- guide/dev_guide.mvc.understanding_model
- guide/dev_guide.mvc.understanding_view
- guide/concepts

Now we have:
- guide/introduction: High level description of Angular with the key benefits but without code or any concrete concepts
- guide/concepts: explains all important concepts with a simple example and contains deep links to the other parts of the guide.

 All the old information was moved into existing documents or deleted when they were duplicates.

 ## Automatic Initialization

 Angular initializes automatically upon `DOMContentLoaded` event or when the `angular.js` script is
 evaluated if at that time `document.readyState` is set to `'complete'`. At this point Angular looks
 for the {@link api/ng.directive:ngApp `ng-app`} directive which designates your application root.
