	// version:
	//		1.5 (deprecated)
	// summary:
	// 		Handles File Uploading to a server (PHP script included for testing)
	//
	//		FileUploader is now a WIDGET. You do not have to pass a button
	//		in. Passing a button is still supported until version 1.5 to maintain
	//		backwards compatibility, but it is not reccomended. Just create your
	//		uploader like any other widget.
	//
	// description:
	//		If the correct version of Flash Player is available (> 9.0) , a SWF
	//		is used. If Flash Player is not installed or is outdated, a typical
	//		html fileInput is used. This process can be overridden with
	//		force:"flash" or force:"html".
	//
	//		FileUploader works with Flash 10.
	//
	//		The button styles are now recreated in Flash, so there is no longer
	//		using an invisible Flash movie with wmode=transparent. This way the Flash button
	//		is actually placed inline with the DOM, not floating above it and constantly
	//		resetting its position. The "Windows Firefox clickable bug" should be fixed (and
	//		hopefully some Linux problems).
	//
	//		The HTML button is created in a new way and it is now inline as is the
	//		FLash button. Styling is much easier and more versatile.
	//
	//	Dependencies:
	//		FileUploader no longer uses FileInput.css. It now uses FileUploader.css
	//		See requires for JavaScript dependencies.
	//
	//	NEW FEATURES -
	//		There are a ton of features and fixes in this version.
	//			Disabled: Can be toggled with widget.attr("disable", true|false)
	//			Submit: A convenience method has been added for if the uploader is in a form.
	//					Instead of submitting the form, call uploader.submit(theForm), and the
	//					Uploader will handle all of the form values and post the data.
	//			Selected List: If passing the ID of a container, the Uploaders will populate it
	//					with the selected files.
	//			Deleting Files: You can now delete pending files.
	//			Progress Built in: showProgress:true will change the button to a progress
	//					bar on upload.
	//			Progress Attach: Passing progressWidgetId will tell the Uploader of a progress
	//					widget. If the Progress widget is initially hidden, it will change to
	//					visible and then restored after upload.
	//			A11Y: The Flash button can be accessed with the TAB key. (The HTML cannot due
	//					to browser limtations)
	//			Deferred Uploading: (Flash only) throttles the upload to one file at a time
	//
	//
	//	CDN USERS -
	//		FileUpload now works with the CDN but with limitations. The SWF must
	//		be from the same domain as the HTML page. 'swfPath' has been exposed
	//		so that you may link to that file (could of course be the same SWF in
	//		dojox resource folder). The SWF will *NOT* work from the
	//		CDN server. This would require a special XML file that would allow
	//		access to your server, and the logistics to that is impossible.
	//
	//	LIMITATIONS
	//		- This is not designed to be a part of a form, it contains its own. (See submit())
	//		- Currently does not in a Dialog box or a Tab where it is not initially visible,
	//		- The default style inherits font sizes - but a parent container should have a font size
	//			set somewhere of the results could be inconsistent.
	//
	//	OPERA USERS -
	//		It works better than the 1.3 version. fileInputs apperantly can't have opacity
	//		set to zero. The Flash uploader works but files are auto-uploaded. Must be a
	//		flashVar problem.
	//
	//	Safari Bug note:
	//	The bug is in the way Safari handles the connection:
	//		https://bugs.webkit.org/show_bug.cgi?id=5760
	//		I added this to the virtual host in the Apache conf file, and now it
	//		works like a charm:
	//		BrowserMatch Safari nokeepalive
