- Updated how byte arrays are represented in the toString() method in the JSONObject. Byte arrays are now Base64 encoded.
 - Fixed NPE when dealing with null dates in the update() method in the Recordset class. - Updated the toByteArray() method in the Value class to check for Base64 encoded strings. git-svn-id: svn://192.168.0.80/JavaXT/javaxt-core@1570 2c7b0aa6-e0b2-3c4e-bb4a-8b65b6c465ff
