Use new struct to check status & Remove IAP_ENVIRONMENT

Browse Source 
Use a new struct called `HttpStatusResponse` to check the status code returned in the receipt. This is ios-type independent and will redirect the receipt to sandbox if needed.

Following Apple's recommendation, always hit production and then sandbox. There is no more need to specify which environment to hit.
