PATCH: correctly create and delete messages in sequence diagram

This bug was caused by
1. registering the message *twice* with the objects upon creation from toolbar
2. not checking for this in the registration functions, although relying on
correct use
3. not using the contract of an associationwidget correctly in the toolbar
widget. (activate() may *only* be called after serialisation, not after 'plain'
construction.

This patch fixes these three issues and maintains the contract.

NOTE to developers : this patch comments out the old code, you may remove the
commented parts all together before committing in svn.
