Subject: [PATCH] [IMP] website_sale_wishlist: quantity in js sessionStorage

The session value is updated each time the user modifies the wishlist.
The number is also updated when the user go on the wishlist page or if
the value is different from that of the HTML content (if the user does
undo in his history).
