title: How can I change devise alert message for password_confirmation
body: <p>I am trying to change the alert message from the standard "doesn't match Password" to "The passwords do not match" but I can't figure out how to do it.  I've already tried adding the following to my devise.en.yml file:</p>
  
  <pre><code>activerecord:
      errors:  
        models:
          user:
            attributes:
              password:  
                confirmation: "hey you billy"
                blank: "cannot be blank."
                invalid: "this password be invalid yo"
  </code></pre>
  
  <p>but this does not work.  The blank message works but confirmation does not.  Does anyone know how to fix this?</p>
