Patch v1

Attached the first steps. EMF and GMF editor now provide a context menu that allows locking the selecteed objects. 

This combined patch also contains some test to verify the new behavior.

Additional tasks to do:
- provide better (changeable) coloring for the effected objects
- provide changeable icons for locked object that can be changed be customers
- provide extendable locking strategies which make it possible to define which objects are effected if one object is locked
- editing locked objects must be prohibited by the UI. Currently only an exception is thrown at commit time.
- enhance tests
