Updated IonicTodo to latest version in Ionic Tutorials using ionic-app-base style

Deleted many unnecessary files.
Accomodated ajoslin's bower technique from ionic-app-base to install the project.
Code pulled from http://ionicframework.com/docs/guide/building.html
However, still has bug in iOS. See:
