Charge amount rounded down

[kd7lxl]

In the payment handler, the order total is rounded down to the nearest dollar before the Stripe Charge is created. This is bad. The Stripe Charge amount should match the order total.

cartridge_stripe/init.py:

    charge = stripe.Charge.create(amount=int(total) * 100,

Better:

    charge = stripe.Charge.create(amount=int(total * 100),
