Lisää SMTP-lähetystuki postilaatikoihin

Browse Source 
Aiemmin sähköpostit lähetettiin PHP mail()-funktiolla, mikä
ei toimi kunnolla useimmilla palvelimilla (SPF/DKIM-ongelmat).
Nyt mailboxiin voi konfiguroida SMTP-asetukset (host, port,
user, pass, encryption), ja lähetys tapahtuu suoraan
SMTP-palvelimen kautta socket-yhteydellä. Fallback PHP
mail():iin jos SMTP-asetuksia ei ole asetettu.

- db.php: smtp_host/port/user/password/encryption sarakkeet
- api.php: sendViaSMTP() socket-pohjainen SMTP-client
- index.html: SMTP-kentät mailbox-lomakkeeseen
- script.js: SMTP-kenttien luku/kirjoitus lomakkeessa
