Improved draft now online

Most of the feedback is now incorporated, especially:

• cleaner API for creating instances of Jython objects
• code examples greatly simplified
  
• agenda improved
• list of books improved
• English proof reading by Gustaf Hansen (thanks a lot, Gustaf!)
  

In summary, the flow of the presentation appears much clearer to me.
Now I really hope that I will be allowed to improve the slides for the conference, too.

Still missing or incomplete:

• Why Jython / Python ?
• Using Java objects from Jython
