auth_username_format changes the username permanently and the  
original username isn't found from anywhere anymore.

I removed the special casing of %d from v1.1. The default is to  
always lookup using %u format. So the original behavior of "args = / 
etc/imap.%d" must now be done as "args = username_format=%n /etc/imap. 
%d". I thought about leaving it, but it was kind of ugly hack and I  
wasn't sure if it would break something if I left it.
