NoMethodError: Subscription.prorate

[yas4891]

There's no method subscription#prorate - yet it gets called in SubscriptionController#update (line 143). The line was introduced by a PullRequest merged on Aug 19 from @hanchang

Sorry about that - the fix (PR #74) is to remove the subscription#prorate method call which I incorrectly assumed would pass parameters to the actual Stripe::Subscription object.

Instead, I've added the proper logic in the processing! method of the Koudoku::Subscription concern so that it passes the config setting for prorating in koudoku.rb.

Hope this does the trick!
