	Added experimental built-in HTTP server. Currently, when a
	client accesses to the server, it responds with the current
	download progress. By default, it is disabled. To enable the
	server, give --enable-http-server option.  To change the default
	port number for the server to listen to, use
	--http-server-listen-port option.
	The response HTML is very simple and refreshes it self each 1
	second.  Because of this refresh, you see flicker in normal web
	browser such as Firefox.  I recommend to use console-based
	browser such as elinks, w3m.  To connect to the server, run
	'elinks http://localhost:6800/' while running aria2. Please
	replace port number '6800'(which is default) with your
	preference.
