Added a more automated way to create Sent and Trash folders since Cyrus doesn't create them during account creation. Also put in a hack to subscribe you to your INBOX as a work around for the fact that Cyrus doesn't have you subscribed to your INBOX automactically. This is all working with the $imap_server_type var, and shouldn't affect any other server type. The options only show up in the folders link if you do not have an INBOX.Sent or a INBOX.Trash.

I need to clean up the code, so don't but it seems to work.
