missing node on overlay after _handleSend()

[goriol]

dojox.form.FileInputAuto?._handleSend() removes this.overlay.firstChild (that was previously changed to display the upload message) but never restores the original blank text node (" ). Thus, when _sendFile() is invoked another time (if an error occurred at first attempt), it will fail trying to remove a missing node.

I would suggest to change:

	_handleSend: function(data,ioArgs){
		// summary: The callback to toggle the progressbar, and fire the user-defined callback

		// innerHTML throws errors in IE! so use DOM manipulation instead
		this.overlay.removeChild(this.overlay.firstChild);

		// ...
	},

into:

	_handleSend: function(data,ioArgs){
		// summary: The callback to toggle the progressbar, and fire the user-defined callback

		// innerHTML throws errors in IE! so use DOM manipulation instead
		this.overlay.removeChild(this.overlay.firstChild);
		this.overlay.appendChild(document.createTextNode(" "));

		// ...
	},
