[Checkins] SVN: z3c.form/trunk/ - Implemented IDisplayForm interface

[Roger Ineichen]

Log message for revision 82559:
  - Implemented IDisplayForm interface
  - Added integration tests for form interfaces. Added default class attribute
    called widgets in form class with default value ?\194?\180?\194?\180None?\194?\180?\194?\180?\194?\180. This helps to 
    pass the integration tests. Now, the widget attribute can also be used as a 
    indicator for updated forms.
