[vb6] IDE-Safety Thunks for subclassing, hooking and more: A new breed

[LaVolpe]

Project updated. Summary of updates:

Major change includes reworking thunks to be smaller overall. Every thunk has destruction code that is nearly identical, along with other code that is very similar. A new "management" thunk was created that will have common-use methods that other thunks and the class can share. Related code was then removed from all existing thunks and also the clsThunks class itself -- now resides in the new thunk.

Functions changed to properties (consistency):
Custom Class: AddrOf, State, IsFiltered, IsManaged
Subclasser: IsFiltered, IsManaged
COM Hook: IsManaged, RefCount

CreateStub removed as public method from these taskers (didn't want these executed by users):
Callback, Custom Class, Windows Hook

New tasker methods (requested enhancement):
Callback: IDEredirectAddr property Get/Let added. See documentation, class comments
-- optional wrapper updated
-- if using TLB in post #25, cannot call these new properties using that TLB

Taskers that can now optionally forward events to bas-modules (optional & use at your own risk)
-- Note: IDE safety reduced when forwarding outside of the host
Callback, Custom Class, Windows Hook, Subclass, Timer

Class reorganized a bit, but every method had significant code changes.
Sample project modified slightly, previous project will work with this updated class.

A sincere "thank you" goes out to HosseinMoradi for enhancement suggestions and working with me offline for brainstorming ideas.
