Add an active class on the active option for thumbs up/down

If I got it right, the patch #3 was supposed to add an 'active' class to the selected option (up or down). However, it didn't quite do it: it was comparing a local $vote_type ('up' or 'down') to a bundle name ('updown'), which was never true.

I rerolled the patch against current dev, enhanced it a bit to cover also yes/no vote and fixed the problem I mentioned. Now it works for me at least.

So now it saves to $has_voted the value of a vote (1/-1), not its bundle.

1. Let's leave the property 'has_voted' unchanged. Let's add a new one 'user_voted'.

-        $vote = Vote::load($vote_id);
-        if ($vote) {
-          $has_voted = $vote->getValue();
+        if ($vote = Vote::load($vote_id)) {
+          $user_voted = $vote->getValue();
         }
       }
       $user_can_vote = $this->accountProxy->hasPermission('cast rate vote on ' . $entity_type_id . ' of ' . $bundle);
 
       // Set the theme variables.
       $output['rate_vote_widget'] = [

         '#can_vote' => $user_can_vote,
         '#has_voted' => $has_voted,
+        '#user_voted' => $user_voted,

2. I changed the name of the 'active' class to 'rate-voted'.

3. I changed the css for the 'Thumbs Up / Down' widget.

#11 works and looks good and I could've RTBC'd it, but instead added the missing comment lines to the twig templates.

Sorry, the #13 patch file was left out.

LGTM

Thanks!
