skipTransitionOnSameView settings to skip transition within same view

Try to resolve issue discussed on https://groups.google.com/forum/#!topic/durandaljs/LlFYkgbeehY.

On your shell, put `skipTransitionOnSameView: true` inside compose binding parameter, looks like this:

```
<!--ko compose: { 
        model: router.activeItem, //wiring the router
        afterCompose: router.afterCompose, //wiring the router
        transition:'entrance', //use the 'entrance' transition when switching views
        cacheViews:true, //telling composition to keep views in the dom, and reuse them (only a good idea with singleton view models)
        skipTransitionOnSameView: true
    }--><!--/ko-->
```

That will makes activate module item within same view not causing transition to be played.
