- Fixed bug where Statement.setMaxRows() was a global setting. Now
          limited to just itself.
        - Changed LargeObject.read(byte[],int,int) to return the actual number
          of bytes read (used to be void).
        - LargeObject now supports InputStream's!
        - PreparedStatement.setBinaryStream() now works!
        - ResultSet.getBinaryStream() now returns an InputStream that doesn't
          copy the blob into memory first!
        - Connection.isClosed() now tests to see if the connection is still alive
          rather than if it thinks it's alive.
