[sugar] Sugar restart lost Journal, and some customization

[Mikus Grinbergs]

G1G1.  Joyride 1848.  Made the mistake of pressing ctl-alt-erase.

When the new Sugar came up, it asked me for the Name and the Colors. 
I found that I had lost the previous Journal contents, and the Main 
screen's activity ring.

I don't depend upon the Journal.  What got me upset was that from 
then on, if I did a manual edit of /home/olpc/.sugar/default/config 
and then rebooted the XO -- this file's content was RESET to however 
that earlier Sugar "restart" had set up this file.  [I had hoped 
that this file's contents would *persist* between reboots.]

Reinstalled Joyride, to try to ward off this behavior.  But will NOT 
again attempt to "restart" Sugar (as it advises) after changing 
sugar-control-panel -- will instead be rebooting from scratch.
