Downloading Scratch project to XO

[Bert Freudenberg]

The simplest would be something like

if [ -n "$object_id" ] ; then
	filename="$SUGAR_ACTIVITY_ROOT/instance/temp.sb"
	copy-from-journal -o "$object_id" "$filename"
	#... append "$filename" to Scratch command line ...
fi

(assuming the Scratch wrapper still basically looks like the Etoys one)
