title: slickjs always show arrows
body: <p>I'm trying to config slick.js to show arrows in any circumstance.</p>
  
  <pre><code>$('.slider-for').slick({
    slidesToShow: 1,
    slidesToScroll: 1,
    arrows: false,
    fade: true,
    asNavFor: '.slider-nav'
  });
  $('.slider-nav').slick({
    slidesToShow: 6,
    infinite: true,
    slidesToScroll: 1,
    asNavFor: '.slider-for',
    arrows: true,
    centerMode: false,
    focusOnSelect: true
  });
  </code></pre>
  
  <p>The problem is when my slider hasn't enough slides do show (in my case, 6)
  If the slider has less than 6 slides, the arrows don't show up. </p>
  
  <p>I know the plugin  works like that, but for other reasons, i need to always show the arrows.</p>
  
  <p>Anyone had to deal with something like that before ?</p>
  
  <p>Thanks.</p>
