automatically subscribing to new folders in gnus

If you use gnus to read your imap, you might find this useful. Gnus does not automatically show new folders created in your IMAP server. However, you can get this behavior by using the gnus-auto-subscribed-groups variable. In my .gnus, I added this (setq gnus-auto-subscribed-groups "INBOX.*") and voila! all my new folders started showing up.
