New git "master" repository

[Ask Bjørn Hansen]

Hi everyone,

Charlie asked a question that reminded me that I don't think I mentioned this:

The canonical git repository is now 

        http://github.com/smtpd/qpsmtpd

I'll get the github people to update things so all the references to 
abh/qpsmtpd (forks etc) will hopefully be automatically updated to point to 
smtpd/qpsmtpd.
