[sugar] Update.1 activities download script

[Chris Hager]

Sorry for posting twice here before, but somehow I didn't receive any 
devel and sugar mails for 2 days... Now seems to work again. :p

I'm just about implementing the script into xo-get, and I was thinking 
on how to do it. Either simply integrating it into xo-get.py (xo-get is 
a 1-file script), or download it on an 'xo-get upgrade' if it's not 
available. This might be smarter, so changes in the upgrade script can 
be made without changing xo-get.

Maybe only make symlinks?

  ln -s /usr/share/activities/*.activity /home/olpc/Activities/

Thanks a lot, this is really useful for me already! Maybe also put it 
somewhere in the wiki... [[Programming Tricks]] :)
