Build 4.0.0.68 of xlsgen includes several fixes :

- when processing XLSX/XLSM/XLSB files with VML streams (comments, ole objects, form controls, ...), there could be HTML fragments right within the XML stream which can cause havoc to parsers. This fix correctly handles <br> tags and so on.

- table copy maps internal formulas correctly. Internal formulas are formulas in tables referring to one or more of its columns by name (also called structured reference in Excel speak language).
