getOriginPrivateDirectory is not a name that's friendly to partitioning

[annevk]

It assumes that the storage key will forever be an origin, which is less and less the case.

[inexorabletash]

Good point. Any name suggestions?

[annevk]

getStorageDirectory() or some such? Or navigator.storage.getDirectory()?

[mkruisselbrink]

I'm leaning towards either navigator.storage.getDirectory(), or moving the entire API surface to a FileSystem namespace (as suggested in #210), and thus ending up with FileSystem.getPrivateDirectory().
(i.e. either 6192c45 or 345af0a)

navigator.storage seems a bit weird, since none of the other storage APIs are exposed via navigator, but that's probably okay. After all what existing APIs do via a singleton on the global seems to be explicitly against TAG guidance for new APIs.
