xo-get update

[Chris Hager]

Hey all!

I have updated xo-get to use http://wiki.laptop.org/go/Activities as 
repository. The tool includes all activities with downloadable .xo 
links, and follows [[Image:...]]-links to the real source. Currently 
there are 43 Activities installable.

You can install xo-get this way:

    wget xo-get.olpc.at
    chmod u+x xo-get.py

Started with './xo-get.py', it will first ask for an update :)

More infos: http://wiki.laptop.org/go/Xo-get

Thanks for any feedback!
