[Dovecot] dovecot 2.0 convert script

Since my old config had this:

protocols = imap imaps pop3 pop3s

ssl_cert_file = /usr/share/ssl/certs/imapd.pem ssl_key_file = /usr/share/ssl/certs/imapd.pem

then the convert script should have added

ssl = yes

Just trying to document all the little issues as I find them.
