Pass referrer information to the store for native app banners.
The related application URL is now parsed if it is present in the manifest.
The id is extracted, and compared against any id specified in the manifest,
with an error triggered if they do not match. Any referrer information from
the URL is also extracted, and passed through to the Play Store.
The old AppDetailsDelegate method signature (sans referrer parameter)
is also removed.
