Updating pde.spy.event to latest databinding API

As the planned deletion of the databinding API would break the PDE
build, this is a quick fix to make PDE compile again and to ensure the
event spy still works. This is done under time pressure so I'm sure that
this can be solved nicer (without copying code from the deleted classes
into the event spy).

Fixes eclipse-pde#339
