Just one tip maybe would be better to dereference PMethod after assigned

Ok, didn´t think about it.
Reattaching the patch, which this fixed. Now I tested with both nil
and non-nil methods.
IMHO Self.SetWindowLong is not so nice looking, SetWindowLong looks better.
To be on the safe side, I would always call SetWindowLong for GWL_USERDATA, if the
method is nil, you can decide if you want to set it to 0 (nil) or to PMethod pointer
referencing a nil method.
I think it is better to use an atom or setprop (like for WindowInfo). Maybe the user
of AllocateHWnd wants to use the userdata for himself.
