Word 2003 not sanitized properly

Linked issues: #14, #16

When OLE2 (files up to Office 2003) are sanitised, and Macros are removed, the "Workbook"/"Document" entry still knows about them and generates an error or a Warning.

This has no impact on the sanitation process, but displays ugly warnings.

The VB Project information must be stored in the Document/0Table/1Table stream (I don't know yet)
