Title: Let the user finish the transaction with [SimplePurchase finishTransaction:t]

I needed the case where I asynchronously send the transaction receipt to my server for verification. Since plenty of things can go wrong during this period I didn't feed comfortable that SimplePurchase did finish the transaction for me. So I rather want to finish the transaction only if it was verified by my server. May be you find it useful, too.
