Implement the playstore acknowledge purchases methods.

[tbem]

It would be nice to can acknowledge purchases into the play store, with the acknowledge_purchase_product and acknowledge_purchase_subscription methods available on the AndroidPublisherService.

@tbem This is indeed a good idea especially for non-consumable in-app purchases.

Feel free to send a PR for this task.

Hi! I have a PR that should fix this issue.

[henrikholm89]

When will this actually be released? It seems like I have to fork the repo to get this feature right?

[jnbt]

@henrikholm89 A new gem version 0.3.0 was released yesterday by @christophweegen

@jnbt Sadly, acknowledging a subscription is not included in 0.3.0, if it is not in your stash, I would be glad to try to help with this issue.
