      Tag: Zope3-Server-Branch
	IVFSCredentials.py 
Log Message:
Okay, it finally works! We have a Publisher FTP server again. All the basic
functionalitry is there, from dir listing, file transfer to security.

I punted for now on recognizing file endings, since Jim wants to write a 
proposal for that next week. Also, I did not solve the statistical file
information problem, since this takes some more research.
