Consistent Connection and Transaction notes() POD

Qpsmtpd::Connection::notes() and Qpsmtpd::Transaction::notes() have
identicaly functionality; however, the POD documentation for Connection
notes is fairly brief while the documentation for Transaction notes is
longer and more helpful.  This updates the Connection notes documention
to be consistent with its Transaction counterpart.
