Did an initial pass at this for EML200DataSource actor.  Uses a JTable (with
simple sorting).  Have not tried it with _big_ datasets - might encounter some
problem there - all in memory.
Preview is accessed from right-click context menu on actor. The
org.kepler.actor.preview.Previewable interface should be implemented by any
actor that wishes to expose a "Preview" of some sort.  public void preview()
method is the only requirement for implementing the interface (thus far).
If there is an attempt to preview a non-Previewable actor, a warning message is
displayed indicating that previews are not yet supported for that type of
actor.
