[vos-d] Message handler problem

[Peter Amstutz]

That's something that was introduced by the new event tables 
implementation in 0.24.  The solution is to make the registration 
function a templated class, and for the subclass to call the base class 
registration function with the subclass type to ensure that the method 
handlers are associated with the subclass as well as the base class.
