Fixed password reset token not working for Devise in current Errbit build.

The Devise reset password token is passed as ```@token``` from version 3.1 and newer. This breaks the reset password feature in the current version of Errbit because it uses version 3.1.1 of Devise. Read more about it here https://github.com/plataformatec/devise/blob/master/CHANGELOG.md#310.
