Feature/basket

Hello to everybody,

I added the basket with the following functionalities:
- it reads the Basket Service for items
- it is reused on both ALaCarte screen and checkout screen
- it is editable on AlaCarte screen (it has a delete button)
- it is readonly on Checkout screen

Added also the checkout screen with all the fields for delivery information (no validation on it). 
Also added a page to give our thanks to the clients.

Again, I would need this pull request quite fast, because I already started the GoCrazy screen and I am quite blocked because there is no Basket.

Cheers,
Liviu
