title: Alfresco connected user in Alfresco webscript
body: <p>In a Alfresco webscript I want to get connected user. In share webscript I know there is a root object called <code>"user"</code> which allows us to  get  connected user properties. </p>
  
  <p>But in Alfresco webscript this root  object is undefined. Actualy I have to pass connected user's <code>userName</code> as argument of the webscript url. </p>
  
  <p>Is there a way to directly get user properties in alfresco webscript (javascript) ? </p>
  
  <p>I'm using alfresco 5.0.d. </p>
