new registered users should be assigend to roles user and editor

[cswertz]

According to
http://localhost:3001/users/edit/
new registered users are not assigned to any role. I assume that means they can't do nothing (or maybe a bit more). I'd suggest that new users are attached to user and editor.
A perfect solution would be to add the possibility to edit the roles that are attached to new users in
http://localhost:3001/users/roles/edit/
A new binary field in the database like "attachToNewUser" would be necessary.
If that seems reasonable, I'll alter the database accordingly.
