title: Inject referrer action via action filter?
body: <p>Is there a way to inject the referrer action from an action filter? 
  Lets say I have a view that comes from action X. In dies view I call action Y and I want to redirect again to action X. (There are multiple X actions that call action Y). I thought that it could be nice if I had a parameter call referrerAction and an action filter that filled it with the previous action. Is it possible?</p>
  
  <p>Thanks.</p>
