Title: Support for setting and sending shared secret

Sorry, dorky. one more necessary change to make autorenew subscriptions work. apple needs a shared secret code for these: http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/RenewableSubscriptions/RenewableSubscriptions.html#//apple_ref/doc/uid/TP40008267-CH4-SW2

I'll bet there will be one or two more changes in the coming days, if i'm being pessimistic.
