Downloading Scratch project to XO

[Philipp Kocher]

Hi Bert, John

There is a bug in copy-from-journal, it is adding an additional dot 
before the file extension. Otherwise it is working.

[olpc at localhost ~]$ copy-from-journal -o 
07474cf4-4883-4ded-a994-ab5511cfc29c /tmp/test.sb
/home/olpc/.sugar/default/data/07474cf4-4883-4ded-a994-ab5511cfc29c -> 
/tmp/test..sb

My workaround in scratch-activity looks like this:
if [ -n "$object_id" ] ; then
	filename="$SUGAR_ACTIVITY_ROOT/instance/temp.sb"
	copy-from-journal -o "$object_id" "$filename"
	filename="$SUGAR_ACTIVITY_ROOT/instance/temp..sb"
else
	filename=""
fi
# run Squeak VM with Scratch image
exec /usr/bin/squeak \
	-vm-display-X11 \
	-swapbtn \
  	-sugarBundleId $bundle_id \
	-sugarActivityId $activity_id \
	ScratchXO.image \
	"$filename"
