/*
 this script allows user to change styles of doc before it has been loaded
 it supposses that:  
  - there are two <link> elements BEFORE this script is included
  - theese <link>s have id="origCss" and id="userCss"
   (because of that my IE6 wasn't able to find them any other way than getElementById)
 usage: via url params
  http://this.html?cssUrl=http://your.css&defaultCss=off
 url params handler is made by yuhuu
