- packager: add signature specific files/contents if workbook->vba_project_signature is set

- vba_project is always set if vba_project_signature is set due to new function workbook_add_signed_vba_project
- rename functional test_macro_signed to test_macro04
- remove dev/vba_code_signing, will be part of Python lib
- remove trailing spaces
