Should be possible for data sources to assert difference #46

It should be possible to assert A owl:differentFrom B in a data source, and for 
this to prevent Duke from ever claiming that A owl:sameAs B.

The JDBCLinkDatabase component in Duke already supports this. If a row (A, B, 
DIFFERENT, ASSERTED) were to appear in the database, Duke would never add an 
owl:sameAs between A and B. However, Duke cannot now get this information from 
the UMIC and into the link database.

To add support for that we'd need to:
  * Add a Collection<Link> getLinks() method to the Record interface, so that records can arrive in Duke with pre-known link information.
  * Add support for populating this data to individual data sources.

Oh, and we also need to update the code so that this gets written correctly to 
the link database.

Alternatively, we could define a LinkSource interface that produces links.

Ok, we now have the LinkSource interface. The next question is how to make use 
of it.
