Update Demo/ and Tools/ directories

[Dennis Benzinger]

Hi!

I'd like to help with updating the Demo/ and Tools/ directories as it is 
suggested in the Python Wiki <http://wiki.python.org/moin/SimpleTodo>.

How exactly should the directories be updated? Should it just be made 
sure that the demos and examples are working or should they be updated 
to use the newest applicable Python features (e.g. the new any/all 
functions)?
