Last commit of the week... Need to implement and test getCocktail(Long id).
Merge branch 'dev_yann' into dev_alexis
Get cocktail with it's ID from the ManagedBean !
Add functions to ManagedBean to display :
	- Buy Cocktail in the cocktails array
	- Display the cart content
It's working !!!! GREAT !!!
Mise en place de l'appel de l'interface CartLocal dans le ClientFacadeBean, it works
