CoreAPI: UnixFS, discerning directories from non-directories.

[djdv]

At the moment, I am relying on an error returned from Cat() to determine the type of object I'm dealing with.
(reference)
I think something like .IsDir() on the UnixFS interface, or something more generic, like .Type on the ObjectStat, containing some value like: Unknown, UnixFsDir, RawData, etc., would be a better alternative than relying on Cat()'s error, if you're trying to use the CoreAPI alone (without dropping into relevant pkg for each node format you wish to handle).

Relevant:
ipfs/go-unixfs#3
#3430

Unixfs coreapi will get a major refactor, I'll take that into account
