Update client side frameworks #17

Update client side frameworks #17

- Frameworks upgraded
Angular 0.9.19 to 1.1.5 (not 1.0.x because this [issue] (https://github.com/angular/angular.js/issues/2256) is only fixed in 1.1.5)
Twitter Bootstrap to 2.3.2

- Polling management has been improved
Remove controllers instanciation in html if route already uses them => less polling instance
Polling are now stopped if you navigate to other page
I use setInterval because karma hangs with $timeout
