Append a MethodField named 'row css method',

to enable setting the CSS class to each table rows.

The method is expected to receive a brain and index as the parameters
then returns a CSS class name.

And I(tatuya) attempt to use the property in the FormPrintout,
to set a style name in a ODF template explicitly.
