Fixed the bug that FtpFinishDownloadCommand does not handle
	timeout. This means it waits for the remote server to send "226
	Transfer Complete" message *without* its own timeout until the
	remote server shutdowns connection(we can detect EOF in this
	case).
	* src/AbstractCommand.h
	* src/FtpFinishDownloadCommand.cc
