Enable sending of registration mails

* enable sending of registration mails to give our users a warm welcome
  and a kickstart into the system's usage
* change some default configuration related to email sending
* also, rework the auto-confirmation of new accounts to use the new-ish
  mechanism provided by Invenio-OAuthClient
