Subject: [PATCH] Change plan subscription to require a new credit card

Fixes Issue #101

We change the Stripe plan subscription code to require a new credit card to be entered every time a user moves from the open source plan to a paid plan. When a customer's credit card fails, Stripe auto-desubscribes the user from an active plan, but (before this change) we would try to resubscribe with the invalid card.
