- Changed interface 'Phonegap.exec' to 'cordova.exec'
- Use paymentWithProduct instead of paymentWithProductIndentifier
because It was deprecated in iOS 5.0
- Changed interface of requestProductData parameters
- Add prefix in NSLog
After restoring completed transactions, the payment queue observer is
notified by a call to either
paymentQueue:restoreCompletedTransactionsFailedWithError: or
paymentQueueRestoreCompletedTransactionsFinished:. This patch
delegates calls to these methods to callback functions on the
plugins.inAppPurchaseManager.
Adds a requestProductsData method to the InAppPurchaseManager which
takes an array of productIds and invokes a single callback with the
results of the SKProductsRequest.
