DEFAULT_REPLY_TO email

[jpic]

Sometimes, the email user is not the mail to reply to ie. in the case when hosting many websites for many users.

In my setup, there is one mail account allowed to send emails, SPF is properly configured for it, but users should receive an email with the Reply-To set to the actual website owner, which might be a @gmail account in which case it is flagged as potential spam.

Can we add a DEFAULT_REPLY_TO setting for use in send_mail_template ?

Seems reasonable. I would be open to reviewing a PR. If you tackle this, please make sure it's backwards compatible and doesn't break if the user doesn't define the new setting.
