title: AutoScroll Toolbar text when using CollapsingToolbarLayout
body: <p>I have <code>CollapsingToolbarLayout</code> with long title with <code>Toolbar</code> inside.
  Because of title is too long, its end is replaced by three dots. The problem is when <code>CollapsingToolbarLayout</code> is collapsed and <code>Toolbar</code> has <code>CollapsingToolbarLayout's</code> title, is still has three dots. I want to make title of <code>Toolbar</code> autoscroll if it's long.</p>
  
  <p>My XML:
