This should be a part of property system, not exposed like that.

Similarly, this needs rework.

It should be possible to reuse same structure for builtin effects.

I'm not sure if we want that. It should be enough to check if CLSID is 
for builtin in Register* call, and redirect to builtin data in 
CreateEffect().
