title: ExtJS align radiogroup in form
body: <p>I am looking for way to setup FormPanel that labels will be aligned left on left side (this is default) and field aligned rigth on right side - they are aligned left...</p>
  
  <p>how long I am dealing with DisplayField, TextField, or NumberField adding</p>
  
  <pre>
  ctCls:  'x-form-element-currency',
  </pre>
  
  <p>where</p>
  
  <pre>
  .x-form-element-currency {
     text-align: right;
  }
  </pre>
  
  <p>do the work and is nicely aligned to right</p>
  
  <p>My problem start when I try to do this same with radiogroup element (I want to have Yes-No radio select)</p>
  
  <p>ctCls: what adding class to the correct (in my opinion) container abowe radiogroup does not make aligment...</p>
  
  <p>What I do wrong ? </p>
