add attributes & operations to the CSV export

[Guillaume]

Hi

The CSV export/import with requirement or classes can be useful to change the elements title, notes, and create new ones via Excel.
However if I use classes or interfaces, I cannot update or create attributes or operations since those aren't exported.

Could this CSV export be improved to have those added?
Could it export directly in an Excel file to avoid the cumbersome CSV import in Excel?

Thanks
Guillaume
