[sugar] importance of Terminal

[Mikus Grinbergs]

Had a case of subdirectories mysteriously disappearing from 
/home/olpc/Activities, including Terminal.activity.  Then found that 
some Sugar scripts would not run from the text console (ctl-alt-F2).
[It also told me "you don't appear to have a connection".]  Ended up 
manually "unzipping" Terminal.xo into /home/olpc/Activities then 
rebooting (to ensure having Terminal in the activity-registry).

Perhaps a non-technical user would be reduced to re-flashing the 
entire XO in this kind of a situation.
