Usage: 
   [[QuoteFortune("AnyPageName","AnyRegEx")]] or 
   [[QuoteFortune("AnyPageName")]] (in which case the default pattern is used) 
 
   if you need to put a double quote(") in the regex, you should put it escaped as \" 
 
Notes: 
   Since whrandom module is not thread-safe and uses the system clock as the seed, 
   which is somewhat coarse-grained, it might be quite possible that the clients 
   might get the same choice for a short time period(apprx. 4ms theoretically, but it 
   might vary according to the system's time call precision).
