[Stephan Richter]

Log message for revision 76939:
  * Provided another hook in edit forms. Now you can change the behavior 
    of applying the data without having to rewrite the complete apply 
    button handler. This turns out to be useful for people not using 
    objects.
  
  * Updated todos.
