Log:
Add a HasUri() method, which allows us to find out if a given backend
has a document with the provided URI.

Remove the restriction that an external metadata backend has to have one
and only one target backend.  This allows them to add metadata to
documents in any backend.

Add a file attributes store to the ExternalMetadataQueryable base class,
as that's a common thing most backends will want.
