Mmmmm... probably?

erikchen has rewritten much of the pasteboard support over the past few weeks;
definitely talk to him.

Moving away from PboardType strings is a good thing.

"""
They accept UTIs and pboard type strings. In a future release they may take only
UTIs. 
"""

Not only that, trying to set the data/types directly makes the assumption that
we are setting all the correct types/metadata, which historically we have been
bad at. Any object that conforms to NSPasteboardWriting should be directly
written to the pasteboard.
