* XML_RPC base64 value class. Instances of this class represent base64-encoded string scalars in XML_RPC
*
* To work on a compatible way with the xmlrpcext backend, we introduce a particular "nativeValue" which is
* a standard class (stdclass) with two public properties :
* scalar => the string (non encoded)
* xmlrpc_type => 'base64'
*
* The constructor can be called with a "classic" string or with a such object
