BUGFIX - Bound events to the view model
Add StartView so it's possible to go back to the Home page

* Define start-template in index.html
* Define StartView as simple view
* Include StartView.js in index.html
* Update AppRouter to display bookList on initialize
* Reroute root path '/' to StartView
Rename AppRouter to main.js (it will contain the AppRouter and some global code as well)
Rename js file inclusion in HTML to main.js
Define #close method in Backbone.View.prototype to properly kill any View avoiding memory leaks
