Can not restore individual purchase

[mikey0000]

In line with apple docs and good usability there does not seem to be a way to restore a single purchase.

Thanks for the report! I don't have much time to look into this at the moment but you are right, this feature is useful in the case of IAPs with associated downloadable content.

If you end implementing this, could you submit a pull request?

Sure thing, I plan to if I can find the time. ;-)

Please do take a look at https://github.com/boost/CargoManager
and commit boost@fa51152

I've implemented saving downloads and am happy to do a pull request for any of that work. (some of it probably isn't pull request quality)
