title: Joomla 3 can't add <script> to article
body: <p><strong>Joomla version:</strong> Joomla! 3.3.6 Stable [ Ember ] 01-October-2014 02:00 GMT</p>
  
  <p>I want add js script to one my article. I'm using TinyMCE editor to edit article.</p>
  
  <p>In TinyMCE plugin field <strong>Prohibited Elements</strong> I filled with dummy text, now it contains "cms123", I removed "script,applet,iframe".</p>
  
  <p>I checked <strong>Global Configurations</strong> -> <strong>Text Filters</strong> for <strong>Super Users</strong> I have set it "No Filtering".</p>
  
  <p>But when I'm trying to save my article with js code, joomla removes my tags <code>&lt;script&gt;</code> from my article, also I checked with <code>&lt;iframe&gt;</code>, joomla replaced this tag with <code>&lt;i-frame&gt;</code> tag... I'm really confused, I can't understand what is wrong. </p>
  
  <p>Can anybody help me?</p>
  
  <p>Thanks.</p>
