 /**
  * Turns all urls and email addresses into clickable links. The "$link" 
  * parameter can limit what should be linked.
  * 
  * Options are "all" (default), "email_addresses", and "urls".
  *
  * Example:
  * 
  *   <?=$text_helper->auto_link("Go to http://www.akelos.org and say hello to bermi@example.com");?>
  *   //outputs: Go to <a href="http://www.akelos.org">http://www.akelos.org</a> and
  *     say hello to <a href="mailto:example.com">bermi@example.com</a>
