This is a patch which changes python's mailbox.Maildir class
to move processed messages form new/ to cur/. Although not 
expicity stated in http://cr.yp.to/proto/maildir.html 
all applications using Maildirs I'm aware of move messages 
form new/ to cur/ after the first reading of a message.
This patch creates the same behaviour in python.
