update to devise 3

The new token logic for confirmation emails requires users to use @token
instead if @user.confirmation_token in mailer views.

Note that this commit removes the token_authenticatable option for

devise: sign in user after account confirmation

This is potentially unsafe, but removes the necessity to login after
the link in the email was clicked.
