  * Pop-up/cookie scripts for fass.se polls 
  * Jonas Ladenfors 2005-04-12
  *
  * To set timeout date for when the pop-up and cookie should "be nomore" change the value in "expDate"
  * 
  * You can use two functions, each function has it´s own separate cookie.
  * 1. enkatPopUpBodyCreator - Should be placed in the onLoad statement of the index page and produces a popup window or a focus on the search form
  * 2. showPollLink - Shows a small img link for people with popup blockers.
