2008-02-11 Tatsuhiro Tsujikawa <tujikawa at rednoah dot com>

	Added the ability to stop aria2 itself when given time has 
passed
	from start. Use --stop option to specify time in minutes.
	When 0 is given, this feature is disabled.
	* src/OptionHandlerFactory.cc
	* src/TimeBasedCommand.h: Make _interval protected scope.
	* src/HelpItemFactory.cc
	* src/option_processing.cc
	* src/prefs.h
	* src/FillRequestGroupCommand.cc: Evaluate _e->isHaltRequested()
	before calling RequestGroupMan::fillRequestGroupFromReserver().
	Without this modification, the result list shows "ERR" when 
aria2 is
	stopped by --stop option. It should be "INPR".
	* src/DownloadEngine.{h, cc}
	* src/DownloadEngineFactory.cc
	* src/usage_text.h
	* src/TimedHaltCommand.{h, cc}: New class.
