	Added options to load/save the server's performance/status to a	
file
	and the timeout to drop their data.
	--server-stat-of=FILE specifies the file to which performance 
data
	is saved.
	--server-stat-if=FILE specifies the file to read previously 
saved
	by --server-stat-of option. Might be used with 
--uri-selector=feedback.
	--server-stat-timeout=TIMEOUT specifies timeout to invalidate 
the data.
	TIMEOUT is specified in seconds and the default value is 
24hours.
