Adding forward slashes to menu item routes to avoid blink effect on route changes

When Yeoman's scaffolding process for a new AngularJS finishes you'll have an app that blinks when you click on any menu item. To see the effect happening, try to scaffold a new app and click on About and them Home menu items. You'll see the screen blinking.

The browser is understanding the action as a whole new HTTP request, I'm not sure why, but changing the Home route to `#/` avoid the annoying effect.
