Updating Passwords and Emails When Using Active Admin and Devise

With Active Admin and Devise, we want to: \* Skip email confirmations \* Require password and email confirmations, but only when changing the email or password This code supports our requirements: ```ruby ActiveAdmin.register User do controller do def update if params[:user][:password].blank? params[:user].delete("password") params[:user].delete("password_confirmation") end if params[:user][:email].blank? params[:user].delete("email") params[:user].delete("email_confirmation") end super end end before_save do |user| user.skip_confirmation! user.skip_reconfirmation! end end ``` [See the Active Admin DSL for details](https://github.com/gregbell/active_admin/blob/master/lib/active_admin/resource_dsl.rb)
