removed console.logs
Removed the view-caching technique, opted for a CSS .hidden class, as suggested by @jashkenas.
 Fixed for both standalone & requirejs versions.

 Changes in short :
 Router ->
    Triggers a collection 'filter' event, causing hiding/unhiding of todo view items

 AppView - >
    Added two simple functions filterAll & filterOne & the relevant events.
    The latter toggles visible on the view

    addAll ->
    	calls addOne forEach todo, filter logic is gone

    addOne ->
    	stores the view in the model for convenience

 TodoView ->
 		toggleVisible function that toggles .hidden CSS class, called from render() or from AppView.filterOne

Hope this gets backbone father's approval stamp!
Decoupled view reference in model. Model tiggers event "visible" that view is listening to
