	Implemented auto protocol detection.
	Now you can do:
	aria2c -Z http://host/file file1.torrent file2.metalink
	(Note: -Z option is required for auto protcol detection.)
	Then aria2c downloads 3 files simultaneously:
	1. http://host/file
	2. file1.torrent <-- read local torrent file
	3. file2.metalink <-- read local Metalink file.

	Same thing goes with -i option. Assume your uris.txt contans:
	http://host/file
	file1.torrent
	file2.metalink
	Then you can do: aria2c -i uris.txt
	(Note: -Z option is not needed if -i option is given.)
