/* Change log:
 * version 0.1:
   + Released in userscripts.org
 * version 0.2
   + Script runs now also on the "scripts" and "script comments" pages
   - Fix bug when detecting user's nick (don't use the word 'name' for a global variable,
     this is is the same as window.name and it is persisted across pages and windows!)
