Sending html mails with text fallback

[peteruithoven]

I understand an email can contain both a html and a plain text version. Where the users email client decides which one is shown.

Nodemailer makes this easy because you can simply set both: https://nodemailer.com/about/

With the current superlogin config however we need to choose, because we set one template and one format type: https://github.com/colinskow/superlogin/blob/master/config.example.js#L105-L108

Couldn't it support both using htmlTemplate and textTemplate config options? For backwards compatibility template and format could still be supported.
