Build 4.0.0.31 of xlsgen is a fix pack made of the following :

- better preservation and setting of calculation properties (XLSX/XLSM/XLSB files)

- proper preservation of dialog sheet types (Form controls) (XLSX/XLSM/XLSB files)

- fixed mime type for international macrosheet sheet type (XLSX/XLSM/XLSB files)

- registerCOM.bat fixed (works in any folder) and added to both 32-bit and 64-bit setups because after all manual COM registration requires the .bat script technique for operating system such as Windows 7 and above.
