title: In Sitecore powershell, can you make an item unpublishable
body: <p>In Sitecore Powershell for Sitecore 7.2...</p>
  
  <p>Is it possible to set the "Publishable" rights on given items (to make them unpublishable)?</p>
  
  <p>Specifically, I wish to automate the process of: selecting an item, opening <code>Publish &gt; Restrictions &gt; Change</code>, clicking the Item tab, and unchecking the "Publishable" box.</p>
  
  <p>I've tried find that property of an item with no luck. I thought this might work, but "__Publishable" is not correct:</p>
  
  <pre><code>(get-item -Path master:/sitecore/content/Path/Home/About-Us)."__Publishable"
  </code></pre>
  
  <p>Is there a way to make Powershell report ALL of the properties of an item?</p>
