Mailer checks the SMTP server's certificate (trust and name; no revocation
check). New config setting AYANOVA_SMTP_ACCEPT_ANY_CERTIFICATE accepts any
certificate (boot warning, shown in server info, manual page).
The notification settings GET returns ******** instead of the SMTP
password; a PUT with ******** or empty keeps the stored password.
F30 and F31 fixed. Changelog and manual updated.
