Subject: Fix pen color bug

Color problem -
 Weird color behavior -
    * Add a box, and a pen to the box. Let some points be plotted.
    * After a bit of time, remove the box, and the attached pen
    * Exit using Stop button, and thus save to journal
    * Restart the above journal project.
    * Now add a box, and a pen to it.
    * Notice that the points plotted before change color to the new box's color.
Also, fixed the destroy tool's malfuntioning bug, caused by track_indices.

Solution: Save tracked_bodies too.
