title: Ionic 2: make ion-list items smaller
body: <p>There is a similar question <a href="https://stackoverflow.com/questions/30723254/how-do-i-make-items-in-an-ionic-list-smaller-less-tall">here</a>, but it pertains to ionic 1 where the <code>ion-item</code> still has <code>ion-content</code>. In ionic-2 there is not <code>ionic-content</code>. I've tried changing the height/padding/margin of the actual <code>ion-item</code>, and the class <code>item-inner</code> and can't seem to get a uniform "skinny-ing" of the ion-items. </p>
  
  <p><strong>Question</strong>: How do I make the ion-items in an ion-list skinnier/smaller/not as tall in ionic 2? Ps. this is using ionic 2 beta 10 </p>
