set builder only if null

[Marco-Sulla]

In Query.java, under newResultSetHandlerFactory(), we have

    if(builder==null) builder=new DefaultResultSetHandlerFactoryBuilder();
    builder.setAutoDeriveColumnNames(this.autoDeriveColumnNames);
    builder.setCaseSensitive(this.caseSensitive);
    builder.setColumnMappings(this.getColumnMappings());
    builder.setQuirks(quirks);
    builder.throwOnMappingError(this.throwOnMappingFailure);

I think it should be

if(builder==null)  {
    builder=new DefaultResultSetHandlerFactoryBuilder();
    builder.setAutoDeriveColumnNames(this.autoDeriveColumnNames);
    builder.setCaseSensitive(this.caseSensitive);
    builder.setColumnMappings(this.getColumnMappings());
    builder.setQuirks(quirks);
    builder.throwOnMappingError(this.throwOnMappingFailure);
}

so you can pass a completely customized builder.
