Now that I have seemed to have fixed the INBOX issue with courier/uw,

enabling this code actually does good in uw (it hides the mail/ non-select
folder), and makes the folders all line up.  In courier, folders no longer
appear (though they still are) subs of inbox... should we change this?

Retested code with exchange, cyrus, uw, and courier, all seem good now.
