title: Inline style of tab panel header in PrimeNG tab view
body: <p>My app runs PrimeNG 1.1.2 and Angular 2.4.1. In my template I use a PrimeNG tab view with corresponding tab panels and respective headers. For a certain reason I want to style the appearance of the tab panel header.
  For instance, say I want to set its font color to green:</p>
  
  <pre><code>&lt;p-tabPanel header="Bezier Curve" [selected]="true" 
  [headerStyle]="{'color': 'green'}"&gt;
  </code></pre>
  
  <p>However, this style does not apply and the font color doesn't change</p>
  
  <p>Any pointers what I am missing?</p>
  
  <p><strong>Edit</strong>:
  <code>font-color</code> replaced by <code>color</code></p>
