The new registration process of Astakos allows to verify the new
user's email before actually activating the user:

1. User signs up providing an email
2. A verification email is sent to the user (with verification link)
3. A corresponding message is shown on the Astakos web page
4. If the user follows the link he/she gets 'verified'
5. The new user is now verified=True, active=False
6. If moderation=False or the admin activates the user manually then
   the user gets verified=True, active=True and is granted access to
   the system

This commit changes the message on (3) to reflect the above changes.
