tool to remove VBA password protection

[decalage2]

VBA projects may be protected with a password. That password is only enforced by MS Office, the VBA source code is not actually encrypted. Therefore, it should be possible to remove that password to unlock the VBA source code.

According to @bontchev: "you have to edit the PROJECT stream and remove the ID, CMG, DPB and GC lines."

At least two options:

• improve olefile to be able to write MiniStreams (the PROJECT stream is usually smaller than 4KB)
• use pywin32, which is only available on Windows
