Instead of using the IVsProjectCfgEventsHelper object we have our own little sink and call our own helper methods
similiar to the interface. But there is no real benefit in inheriting from the interface in the first place.
Using the helper object seems to be:
a) undocumented
b) not really wise in the managed world
