Up to [LON-CAPA] / loncom / interface

	Fix for bug 3621 (plus unmentioned bugs 3621.1, 3621.2, etc.
	Fixes lost select mode while uploading files in portfolio space,
	as well as creating directories, and navigating directories.
	Also, fixes lost destination window (in javascript) so after
	navigating, uploading, etc., selected files are returned to
	parent window.
