Feature/go crazy

Hello,

These are the new features that are commingwith this branch:
- the 2 go crazy screens for selecting layers and toppings
- after selecting layers, a dropdown can be used to add toppings for each layer
- basket was updated to show ingredients for "go crazy" pizzas
- some changes on the basket service on how the data is saved and how the price is calculated when having ingredients
- when using partial views "onload" was replaced with "ng-init"

Cheers,
Liviu.
