Let choose vud node view behaviour

There was an error in:

- hide the voting links(default)
- show the voting links, but show a deny message

The two behaviours should be:
- hide the voting widget(default)
- show the voting widget, but show a deny message on clicking at its voting links

I'll start working on this, but this is going to be dependent on the patch already rolled on #807928: Use modal div instead of popup at denying vote

let's work on test before #812896: make tests work again!

Here a patch which depends on #807928: Use modal div instead of popup at denying vote.

Now, you can choose if you want to use the modal div or to avoid showing the voting links.

I'm commiting this, so we can have a beta1 in the next hour ;-)
