Title: Allow server-side verification of transactions.

Hi! Thanks a lot for this handy library.

I modified the source so that the raw `signedData` and `signature` strings are stored in the BillingDB. This way I can recover the transactions in my `onPurchaseStateChanged` callback through `BillingController.getTransactions(this)` and send to my server all the information needed to process the transaction **and perform its verification**.

It's a small modification, but I think most user will look after this feature.
