follow_link_title needs to extract $link from $variables

Hi guys,

The tooltip function goes like this:

function follow_link_tooltip($title, $variables) {
  // No need to run through t() since both of these already have.
  return follow_link_title($link->uid) .' '. $title;
}

As you may notice, $link is not defined. Did you mean to use $user->uid or just 0 (at this time NULL is being passed.)

Thank you.
Alexis
