Add a different "key" structures to prevent mistakes with indexes.
Unregister the delay bindings when the source is released.
Store the FieldId, in the source itself. That reduces the amount of work when loading the view.
Add option to delay the events initialization (like we do for bindings).
The binding to evaluate "long path" view models are now separated from regular bindings.

Fix event broadcast when a ViewBinding changes.
Add option to reparents the viewmodel class. Force the list to be repainted when the viewmodel changes. That helps with display names when the viewmodel is renamed and with graphpin that needs to be rebuilt.

IsEmpty is renamed to IsValid. It used to be that we wanted to know if there was a source and a path but now the IsEmpty is confusing.
Fix Widget rename for conversion function pins and event pins.

Rename FCreateVariableContext::GetSkeletonGeneratedClass to GetGeneratedClass because it returns the current class it generates and not the skeletal. It will be the skeletal if it's generating the skeletal.

MVVM: Only create properties when needed. Viewmodel properties should always be created (no inheritance). Widget should be created if they are not already. Support BindWidget.
