title: Unity 4.5 - Can't find UI in the "Create" list
body: <p>I've been following a tutorial on GUI buttons, sliders, input fields etc.
  I saw in every video that in order to create a UI button, you go to Create -> UI -> Button (inside Hierarchy).</p>
  
  <p>However it seems like my menu looks different than theirs. Any idea on how to create a UI button?</p>
