serialize.XMLSerializer little patch

[Frank Taffelt <fr...@interface-business.de>]

I made a small fix of the constructor of XMLSerializer.

The following problem occured 3 times:
   public XMLSerializer( OutputStream output, OutputFormat format )
    {
        super( format != null ? format : new OutputFormat( Method.XML,
null, false ) );
        format.setMethod( Method.XML ); // null pointer exception
        setOutputByteStream( output );
    }

if format==null there will be null pointer exception.
I changed
        format.setMethod( Method.XML ); 
to
        _format.setMethod( Method.XML ); 

please cc to me, i am not on the list.

here is the diff:
