 * @todo:
 * - put all strings (id's, classes) in configuration
 * - outsource event's-code
 * - manage cart in cart-class (?)
 * - update bought/cart-count's on menu
 *
 * Ajax-Api:
 * every ajax-call to order/cancel menu's or to add/remove menu's from cart
 * must return the following data in json-format:
 * data
 *   .content            => the rendered Cart for this Day                                             --> to show in facebox on the right
 *   .menu_id            => the ID of the "updated" menu (e.g. ordered, deleted, added to cart ...)    --> to markt the boxes in week/dayView as ordernd/incart
 *   .num_cart_items     => Number of Menus in Cart (not only this day)                                --> to update toolbar
 *   .num_day_cart_items => Number of Menus of menu_id in cart at this day                             --> to decide if box should marked as in_cart or not
 *   .num_order_items    => Number of Menus of menu_id ordered this day                                --> to decide if box should marked as ordered or not
