  Significantly rewritten other replacement scripts to noticably improve performance and add pseudo-threading to gradually replace words on larger pages.
  
  Version: 1.0

  Competing scripts and extensions:
   * http://www.arantius.com/article/arantius/clean+language/
   
   Improvements Needed:
   * Filter HTML attributes (ALT, TITLE, TOOLTIP, etc)
   * Add an interface to manage the words by turning this into an extension.
