Fixed bug (array of orders doesn’t reset) when drop-down orders - now orders updating every time when we’ll click on table.
Now if you’re deleting order in tableView then order will delete on server (DELETE request), but only those which are empty (hasn’t items).

Added method in class Alert:
	+ (void)showHTTPMethodsAlert:(NSError*)error;

Added method in class OrdersDataProvider:
	+ (void)deleteTableOrderWithOrderId:(int)orderId responseBlock:(void (^)(NSError*))callback;

Added method in class RemoteOrdersDataProvider:
	+ (void)deleteTableOrderWithOrderId:(int)orderId responseBlock:(void (^)(NSError*))callback;
