	Implemented download speed based URI selection algorithm.
	Introduced new option --uri-selector.
	If --uri-selector=feedback is given, aria2 uses download speed 
observed
	in the previous downloads and chooses fastest server in the URI 
list.
	Currently at most 10 URIs are considered to introduce 
randomeness for
	finding better servers. The speed is average download speed in 
the
	downloads.
	On the other hand, if --uri-selector=inorder is given, which is 
default,
	URI is tried in order in URI list.
	The usage text for the new option has not been written yet.
