Subject: [PATCH] Update shipping option

Setting list of ShippingOptions like in payments_example.py
shipping_options = [
    ShippingOption(id='instant', title='WorldWide Teleporter').add_price(LabeledPrice('Teleporter', 1000)),
    ShippingOption(id='pickup', title='Local pickup').add_price(LabeledPrice('Pickup', 300))]
gives us [None,None],so It's better add_price to return self
