Notify with anonymised email on new volunteer (#48)

People enjoy the instant gratification of a random alert.

This brings back email notifications to organizers on volunteer sign-up so that relevant people can react as soon as possible.

The email now will contain anonymous data (team name and t-shirt size) and a link for curious people to view the profile.

I have considered adding another email address for such notifications, but it seems unnecessarily complicated.
